HELP Ram 8.4 Radio w/nav conversion

[mrmiller]

I own a 2015 Ram 1500 5.7 Exspress with the 7 speed ac blower motor. Recently purchased VP4 NA head unit with Nav and a Dual Zone Bezel (although I have single zone, this will work)

1st question: AC control modular under passenger side dash for the climate control. There seems to be a dozen revisions of this modular. Which one do I need? (Spent hours even called dealership)
Confused as some are for the 4 speed blowers but 7 speed blower modular 68268186AA replaces about 6 different revisions and is around $500 (that's insane considering the older ones are around $50)

2) Where can I find the wiring conversion harness (modular to new bezel) in 2020. All the threads that I read are 7yrs old. Is the a oem harness I could use as custom made are $150 in 2013?

3) Do I still need the 911 delete resistor or can I disable thru software or OBD? And if so where can I get this?

4) Lastly, the radio I purchased was out of a yard and is locked. They provided the vin. Is there reputable web site that provides the unlock codes?

All feedback and links would be gratefully appreciated. I'm sure there are many looking for updated information.

Thank you!!!

2. @Mpgrimm2 is a forum member and vendor who can make an OEM-like harness for you.

3. I'm told you do and the aforementioned vendor can make it.

Mike has a whole thread on this. https://www.ramforum.com/threads/di...-upgrade-hvac-conversion.135601/#post-1937433

7 speed Universal conversion harness for your truck with part 1 ATC built in is $175 (made with factory spec'd wire and properly crimped terminals). If you want to complete the Single Zone Auto Temp Control (ATC), that's an additional cost (part 2 harness is $60).

Anyone of these will work. Yes. Price new has gone up drastically...

14-17 1500 HVAC Control Module for RAx: 68268186Ax (AB, AC, etc) (7 speed Fan specific models)
** (also replaces 68183973Ax, 68236772Ax, 68239172Ax, etc.)

The main reason I started building these was because of all the unreliable harnesses others were offering originally. New people out there... same problems, less support.

If you'd like to get on the build list to get a harness, feel free to send me a private message/conversation to get things started.

PS: guess which one I build?

Hey Mike G,

I have a 2015 Ram 1500 Exspress and in the process of doing the 8.4 VP4 NA conversion. I bought the dual zone bezel and I belive my truck has the 7speed blower. I also added the 7" Evic. And I just ordered 68183973AB A/C Control Modular.
I was wondering how much would the harness and a 911 delete resistor cost?
You mentioned ATC is additional? Do I need to buy another modular, or is it just something you do with the harness? I thought that's what 68183973AB does?

Thanxs, John
