Yes, this topic has been discussed many times. Mixed answers and mixed results. I'm hoping to get a definite answer as I have many plans for this truck.

I have a 2019 Ram 1500 Classic Express. I'm hoping to upgrade the interior to having a heated steering wheel, seats (ventilated as well if possible) and power lumber support.

I know some truck come pre-wired with stripped options found on higher end trucks. I'm trying to figure out if that's the case with me. I'm hoping someone else in a similar situation could reference this as well.

I checked for a blue wire under the top steering wheel column cover and found a blue plug. It's plugged into a dummy socket.

I've read on a thread that the blue plug means the vehicle is pre-wired for heated steering/seats. For it to function, a new clock spring, wiring harness and steering wheel with a heated element is needed for this to work. As well as the center console buttons and using ALFAOBD or having the dealer flash the codes in the BCM.

On a separate thread, some claim that you also need a driver seat module that supports heated seats and steering. If the module is not present, it will not function.

This thread is being created in hopes that someone could shed a bit of light on my situation, and hopefully to anyone else with a similar issue or wiring setup. Also, information on where the driver module would be plugged/changed if the vehicle is wired for heated seats and steering. If the new module is needed anyways.

As mentioned, my vehicle has the blue plug under the top steering wheel cover. Here is the wiring under my driver seat. I know that the yellow plug is used for airbags / seatbelt chimes, etc... (Unless I'm wrong)

If anyone has any insight on if my truck is pre-wired for heated steering/seats or lumbar support. What I'm missing to make this possible (Other than the parts mentioned above). It would be much appreciated.

If it does seem pre-wired, do I need the heated driver seat module and where would it plug?
(If I in need of another harness), how much would it cost and is it a fairly easy install?

Thanks for your time.

Forum Member and Vendor @Mpgrimm2 can tell you the parts you need and sell you any conversion harnesses you'll need as well. You'll also likely need AlfaOBD to make it work.

I do have AlfaOBD and have quite a few mods done on my truck thanks to it.

The heated steering/seating portion I have no clue where to start really. I don't want to start installing parts with the knowledge I provided above not knowing if all the wiring requirements are met.

I did a writeup on this this year's ago when with the help of 00/RT I was the first person to install the heated/vented seats in an Express/Tradesman. This has become an extremely popular upgrade that had been done by several people. I'm not sure where you got some of your information but there is already a thread dedicated to this. I will answer your questions with facts. I have done this to several trucks.

All 4th gen 13 to 18 come with the column pre wired for the heated steering wheel and adjustable pedals. I would think the Classic is the same but I haven't done a Classic yet. They do this because they install the same column in all the trucks no matter what the trim level is. There will be a connector that is in a dummy slot that's located in the clockspring. This is for the heated wheel Clockspring if equipped.

If your truck has two pink wires with yellow stripes going to the drivers seat yellow seat connector your truck is pre wired. If it doesn't have those two wires it's not. It's that simple.

The heated steering wheel will NOT work without the heated seat. It is controlled by the HSM (Heated Seat Module)

The dealer cannot enable these codes for you if you have an Express/Tradesman because they are not offered/allowed in your trim level. You will need the Alfa tool to enable them.

Regular Cabs are pre wired for the heated/vented seats and heated wheel because they build so few they use the same harness in all the R/C trucks.

Express/Tradesman Quad Cabs and Crew Cabs are normally not pre wired but I have heard some say that some of the Classic trucks have more of the wiring so you may get lucky. I haven't personally seen this.

If you have the wiring you will only need the heated/vented seats, heated wheel, heated wheel clockspring, switch panel and then enable the correct codes.

If your truck is not pre wired you will need all those things plus a conversion harness from M2mods who you can contact in the vendor section of the forum.

You don't need to add the heated wheel in order for the heated/vented seats to work. It can be added later if you chose.

In some cases the vented seats don't play well with the 3" or 5" screen radios. More so with the 3". In most cases people need to uograde to the 8.4" radio but I have seen a few work with the 5".

@Ricks Ram

Very valuable and straight forward information, thank you.

I checked my yellow plugs and I don't seem to have any pink wires with a yellow stripe. I only see a pink wire with a yellow stripe going into a gray connector. (Which can be seen in the third driver seat picture)

These wiring harnesses from M2mods, have you heard any feedback on functionality? Since I'm guessing they'll be controlling stuff such as seatbelt chimes and airbags. I definitely wouldn't want something that could potentially put me at risk or whoever drives my vehicle. Do you happen to know if they're easy to install as well? Or would they require having to disassemble certain parts of the vehicle?

Mike(M2mods) is a member of the forum and builds harnesses for the 8.4 radio conversion, heated vented seats and heated wheel ect. He is one of the guys who helped develop a lot of the harnesses we use. We speak often about ideas and possible harnesses. He is very knowledgeable and builds harnesses that look factory. I have installed several of his harnesses in trucks with no issues. The harness has nothing to do with any of the other features of the seats such as seat belt chimes, occupancy sensors ect. The harness simply plugs into the connector in the pins that aren't occupied. It is strait forward and well labeled. He also has detailed instructions. It is not hard to install at all if you familiarize yourself with the harness before you start. All Laramie's have memory. If you get Laramie seats he can include the memory wiring as well. The passenger side seat will have the power inverter mounted to the seat bottom. You can also make this feature work and install the factory 115v outlet in your dash if you chose. Only the Laramie has memory seats and only the Laramie are heated and vented standard. The Sport looks pretty much the same but they aren't available in memory and the vented feature is an option and not standard. The Bighorn is only available heated if optioned with no memory and most are power adjust on the driver's side only. If you get Bighorn seats make sure they're actually heated. Thet are listed incorrectly all the time. If you install the Laramie seats you can also install memory mirrors and memory adjustable pedals. Plus the truck will have the radio settings and climate control memory. I have all these features working on my 14 Express. It is critical that you get seats from a 13 or newer 4th gen, preferably a newer version as there have been people report issues with the earlier HSM(Heated Seat Module) having glitches in the later trucks. The wiring is identical so you could install a newer version of the HSM if you got earlier seats and had issues with the HSM.

@Ricks Ram
Correct me if I'm wrong since you & STecoD have actually put hands on more of these then just about anyone ...

He doesn't have the wiring to support heated/cooled seats?

- I don't see the matching grey, i401 (20 pin) plug for heated cooled seats coming out of the floor on the driver side (just the yellow i400 and grey i410).

- I don't see the ground wire at i420 pin 21 (yel) passenger side plug.

It would appear he does Not. I always just tell everyone to look for the two pink wires with yellow stripes in the driver's seat yellow connector. If you have that wiring then you at least have the wiring for the heated/vented seats and heated wheel. I tell people to just look for those two wires because it's quick and easy to check and in some cases I have seen the trucks had the 20 pin connector but it was shoved under the carpet for some reason and guys didn't think they had it. You will most likely not have the 4 extra wires for memory seats and mirrors or the 7 extra wires for memory pedals if you want them even if your truck came with the heated/vented seats and heated wheel wiring but obviouslyyou can add that wiring if wanted. This is a pic of the MINIMUM wiring needed for Non Memory Heated/Vented Seats and Heated Wheel. You can see the two pink wires with yellow stripe in the yellow seat connector if it has that it will also have the 20 pin gray connector that's shown in this picture but it's sometimes under the carpet.664bea18a4dd207ff684ab4ec7b1f96e.jpg

@Ricks Ram would I be looking for an extra yellow connector or a set of wires?

I do know there’s a yellow connector under the jump seat. I’m not sure if those could be the potential wires.

And finally, it’s snowing a bit here so I’m not up to removing the seats to check but if I’m correct the best way to check is to remove the seats or is there a plastic trim panel on the door still I can remove to see what wires are running?

Pretty sure yellow is for seat airbags...

I'm not sure if I'm understanding exactly what your question is. You can check to see if you have the correct wiring in a matter of minutes. If your yellow driver's side yellow seat connector doesn't have the two pink wires with yellow stripes you Don't have the correct wiring for heated/vented seats. You can see the yellow seat connector by just moving the seat all the way back just like it's shown in the picture I posted except your truck will not have the gray 20 pin connector next it if you don't have the correct wiring. It should connected to the left( closest to the drivers door) front bottom of the seat with a plastic Christmas Tree Push Pin. If it came lose and is laying under the seat it should still be easy to find as it's the Only yellow connector in your actual seat harness. There should only be One yellow connector going to your actual driver's seat. The gray connectors that are on the right side of the seat near the jump seat have nothing to do with the heated/vented functions. Just look at the picture if you need to verify what the yellow seat connector looks like.

The yellow driver's seat connector is for seat adjust power, heated seat power, vented seat power, seat belt chime, airbag, memory to door module and CAN connector

Thanks for the insight and all the help. How tough do you think the process is to get it all wired up? I do have a 8.4 Inch, Dual zone climate control radio.

Is it all just one big harness that I replace from the driver seat up to the center console?

No, the harness runs from the PDC (Fuse Box) through the firewall and then pins to the seat connectors and a few other places. As I stated you will not be pulling or replacing any of your trucks current harness. You are simply going to add the wiring you don't currently have to it. There are detailed instructions on the M2mods section plus he sends you a PDF with instructions and pictures of the installation. You will need to read the instructions and familiarize yourself with the process. If you do your research you should be fine. It's honestly not nearly as hard as one might think. The harness is labeled so well it would be hard to install it wrong if you pay attention.

@Ricks Ram, @SitKneelBend

Thank you for the time spent to answer my questions. I know this has been discussed before. My main concerns were that if I were to do any crazy work on the truck it would void the warranty as it is still new.

With the answers I received, I'm confident I can make it work with AlfaOBD. I'll be PM'ing @Mpgrimm2 in the future when I'm ready to take on this project. (Most likely when the weather gets warmer in a couple of months) for the wire harness.

My last and final questions would be the following:

1: Is the HSM located in the center console? As I would probably need to buy one and add it?

2: Would the passenger seat be compatible with the changes or do I need extra harnesses etc... I'm attempting to get heated steering and both front seats heated (and ventilated if possible)

HSM is part of the upgraded seat Set (driver side), ie Bighorn heated seats or higher trim. Laramie & higher seats have heated/vented leather (some Sport seats have both, but not all).

Make sure to get 2013-18/classic 4th Gen seats with SRS Airbag tags. 09-12 will bolt up but are wired differently/not compatible and don't have airbags.

There was a slight wiring change to floor length consoles in 2017+ that can affect heated rear seats and panel illumination for the usb hub... Otherwise the same.

As stated by Mpgrimm2 who is also M2mods the HSM is actually mounted to the bottom of the driver's seat and has nothing to do with the center console. The harness he provides makes Everything work exactly as a factory equipped truck would operate and the harness attaches in the factory locations. The driver and passenger seats will both have the power adjust and heated/vented features and the heated steering wheel will work. Of coarse this is as long as you buy seats that have these features. I have seen a rare occurrence where a wrecking yard removed the HSM module before shipping a set of seats out. This is unusual but make sure you verify that whatever seats you buy come with the seat harness and modules still attached. If you buy Laramie seats they will have two models one is the MSM (Memory Seat Module( and the other is the HSM (Heated Seat Module) the Sport and Bighorn seats will only have the HSM as they are not memory capable
