DIY: 2013-2018/Classic OEM Foglight Wiring (& some 09-12 info)

[Mpgrimm2]

DISCLAIMER: I am not a coder, developer, software guru, electrical engineer, etc. but I did sleep at a Holiday Inn Express once!
With that said, all vehicle/electrical mods are at your own risk. Now have fun!

First I want to thank @1500ram12 and many others for their initial work:
- 1500Ram12's: Adding foglights to 2013+ tradesman/slt (2500 bumper parts listed here)
. . . . . and 2013-15 fog lights

- Swine's: LED light bars in bumper (tow hook Location)

I've gotten more than a few requests for a harness to work with the OEM Mopar Foglight Jumper harness in the bumper for 2013-2017 trucks so after a few test installs and 20+ hours of picture and instruction edits here it is:

Dead Link? >>
---------------------------------------------------------------

01. IMPORTANT! Disconnect the Battery before beginning to avoid any potential issues!

02. Partially lift up the PDC by releasing the 4 hold down tabs and then disconnect the 2 PDC connectors closest to the fender so that you can tilt/lift the PDC up out of the way and get to the connector underneath. There is a small “release tab” on the PDC connectors that allows the locking Cam Handle to be pulled away, ejecting the connector from the PDC (Disconnect the other two if you prefer).

03. Locate the Front End Module harness connector. It's a gray 34 pin female connector underneath your PDC. Pry/pop it loose from its “fir tree” mount on the side wall under the PDC. There is an identical black connector on the outside, leave this one alone.


04. Disconnect the two halves of the connector. You will need to remove the white TPA lock plate (Terminal Position Assurance) on the Female side. Remove the lock by inserting a small screwdriver in the sides to pop it out and set it aside (b/w Cam Lever when pulled back to lock position). The other side should already be populated regardless of your package and options.

Here's a video to assist with the connector:

05. Locate the two pin cavities you will need; Pins 2 & 3 (2014 & Up 1500’s) or Pins 23 & 24 (2013 & Up 2500/3500’s). Remove the sealing plugs by pulling them out the back with needlenose pliers or a small screwdriver.

2014 -2018/Classic Ram 1500's:
Pin 2: Wht/Yel wire (left foglight)
Pin 3: Wht/Org wire (right foglight)

2013 -2018 Ram 2500/3500's:
Pin 23: Wht/Yel wire (left foglight)
Pin 24: Wht/Org wire (right foglight)

06. Gently insert the terminals on your harness until they are fully seated/lock, making sure you install them in the correct orientation with the locking tabs. Make sure the seals seat fully in the shell. Then reinstall the TPA Lock Plate and reconnect the two halves. (Ref: Yazaki Sealed User manual p31-33 and p35-39)

07. Tape or zip tie the first few inches of the new harness to the adjacent harness going to the connector for support. Route the ground wire/ring terminal from the harness to the ground lug bolt located on the driver’s side fender near the PDC/Battery, and the rest of the harness out the PDC area, and down the frame towards the top of the bumper.
(Removing the left front headlight may help but is not needed)

 

[Mpgrimm2]

08. Reconnect the 34 pin Foglight connector to the male connector and reattach it to the PDC area side wall. Carefully reconnect any disconnected PDC connectors ensuring they are fully seated and the cam levers are locked down. Reinstall the PDC assembly.


09. “Loosely” secure the Extension Harness to the (2) open 6mm holes on the inside of the frame rail using “fir tree” zip ties. Mount the 4 pin connector to the bumper frame just above the left fog light. Any extra harness length can be shifted to the area under the PDC. Now tighten zip ties.

 

[Mpgrimm2]

10. Plug the Mopar Foglight Jumper harness (Year/Model specific for your truck) into the M2 Mods Extension harness and route it to the left side foglight and along the top of the bumper to the right side foglight locations. Once Routed/adjusted, secure the harness with its pre-installed “fir tree” mounts using the 6mm holes underneath the top of the bumper and around the foglight area support frame. (Extra “fir tree” zip ties will likely be needed)


11. Plug in the foglights.

(Aftermarket lights shown with added
9005/9006 male connector)

 

[Mpgrimm2]

12. Pop out the driver side dash end panel and reach in behind the old headlight switch to push it out from behind. Disconnect it and install your new Mopar Foglight/Headlight switch (PN: 68189154Ax) in the dash. Reinstall side panel.


13. Reconnect the battery.


14. Have the dealer activate the Foglight Sales code (LNJ) or use an appropriate scan/code tool to enable the feature directly in the BCM.


15. Done!

02. Partially lift up the PDC by releasing the 4 hold down tabs and then disconnect the 2 PDC connectors closest to the fender so that you can tilt/lift the PDC up out of the way and get to the connector underneath. There is a small “release tab” on the PDC connectors that allows the locking Cam Handle to be pulled away, ejecting the connector from the PDC (Disconnect the other two if you prefer).


03. Locate the Foglight harness connector. It's a black 16 pin female connector underneath your PDC. Pry/pop it loose from its “fir tree” mount on the side wall under the PDC or slide it off the clip. There is an identical black male connector on the outside, leave this one alone.


04. Disconnect the two halves of the connector. You will need to remove the white TPA lock plate (Terminal Position Assurance) on the Female side. Remove the lock by inserting a small screwdriver in the sides to pop it out and set it aside. The other side should already be populated regardless of your package and options.

05. Locate the two pin cavities you will need; (Pins 7 & 8 (2013 1500 Only). Remove the white cavity plugs by pulling releasing the lock tab at the front of the pin/plug and push them out the front of the connector.

2013 Ram 1500's:
Pin 7: Wht/Yel wire (left foglight)
Pin 8: Wht/Org wire (right foglight)


06. Gently insert the terminals on your harness until they are fully seated/lock, making sure you install them in the correct orientation with the locking tabs. If resistance is encountered, retract the terminal and adjust the angle of insertion. Then reinstall the TPA Lock Plate and reconnect the two halves. (Ref: Molex MX150 Application Guide)


07. Tape or zip tie the first few inches of the new harness to the adjacent harness going to the connector for support. Route the ground wire/ring terminal from the harness to the ground lug bolt located on the driver’s side fender near the PDC/Battery, and the rest of the harness out the PDC area, and down the frame towards the top of the bumper.

Programming with AlfaOBD
( thanks @1500ram12) ...

Reference:
** AlfaOBD
(for activating factory features yourself. See docs linked in OP)

------------------------------------

WARNING:
If you have the AlfaOBD tool, and want to try this (vs dealer activation), please read the AlfaOBD thread OP and enable data logging before you start.
None of the people that have used it for activating the fogslights on their own have had a problem, but proceed at your own risk!


AGAIN: Do this at your own risk. I am not responsible for anything that may happen to your truck as a result from performing these steps.
​

- Connect to your model year BCM (2018 & 19 classic still use the MY16-17 powerNet for now)...

- Select ... "Car Configuration Change"

Enable Foglights:
>> Select ... "Front Fog Lamps Output Present" = select "YES"

*This is actually the 'Ecu Config 01 - CBC Configurable Inputs/Outputs' section.

6/15/20 Update:
Looks like Alexei changed the menus around for enabling the Front Fog Lights... Used to be directly under the car configuration change menu but now you have to go down to the ...


CBC Config I/O - Connector A PIN 01 and Connector D PIN 13: Front Fog Lamps Output Present = YES



Fogs ON with high beams:
>> Select ... "Front Fog Lamp Dropout Enable" = select NO

* This is actually the "Ecu Config 02 - CBC Features" section.

I have enabled fogs with alphaobd. I don't have alphaobd in front of me but had these screen shots saved and am pretty sure this was all that I did








2018 2500 6.4L Tradesman

FYI, I have also made a video on disabling fog dropout... For the visual learners [emoji23]

 

[Mpgrimm2]

Here's how I used my AutoEngenuity tool (ST06 v15.20 w/EI04) to activate the Foglight feature & Disable the Foglight Dropout (keeps fogs on with highs)...

WARNING:
If you have the AE tool, and want to try this, please be aware that the tool has been proven to corrupt/incorrectly write to the BCM with some options that several members have discovered. None of us that have used it for activating the fogslights on their own have had a problem, but proceed at your own risk!
​

Activating with AutoEngenuity

AGAIN: Do this at your own risk. I am not responsible for anything that may happen to your truck as a result from performing these steps.

1. Connect the AE tool to the truck (Key to ON but not running).
2. After selecting the truck, connect to the Body Control Module.
3. Select the "Test Onboard Systems" tab
4. Select Module Configuration from the drop down.
5. Select "Initiate"
6. Accept the warning message.
7. Using the ARROWS on each side of the DONE button, scroll down to "Ecu Config 01 - CBC Configurable Inputs/Outputs".
8. Press Done.
9. Using the ARROW buttons select "Front Fog Lamps Output Present" press Done.
10. Using the ARROW buttons select "SET" and select Exit.
11. Wait for the write to complete.

12. Repeat the above process but this time select "Ecu Config 02 - CBC Features"
13. Press Done.
14. Using the ARROW buttons select "Front Fog Lamp Dropout Enable" press Done.
15. Using the ARROW buttons select "Not SET" and select Exit.
16. Wait for the write to complete.

17. Select the disconnect icon at the top of the AE software.
18. Key cycle the truck, start it up and make sure everything works. If there are any unusual codes, reconnect and clear them with the AE tool, key cycle & recheck.

NOTE: I did have an initial DTC that showed a shorted foglight switch and foglight bulb issue before I activated the fogs and cleared the DTC's. No issues afterwards.

If anything gets real screwy with the configuration, you may have to take the vehicle to the dealer to have the factory configuration reflashed, and start over. "Tinkering" in the configuration with the AE tool is not recommended!

I did something similar to Swine's LED Pod Install, but I don't have the means to make/weld the brackets. See Pictures that follow.

- Swine's: LED light bars in bumper (tow hook Location)

-------------------- Parts List --------------------------

- 7" LED Cree "Spot" Lights ($26 at eBay)
. . or 9" LED Cree Lights similar to Swine's ($32 at eBay)

- (2) 9005/9006 compatible "Male" connectors ($8 5pk at eBay)

..... Pigtails if you don't have the means to crimp the terminals... TOMALL 9005 9006 Male Socket Extension ($6)

- Black RTV sealant (approx $4 at local WalMart)

- (1) Can of Flat Black Acrylic Enamel Spray Paint/Primer

- 4" x 36" 14ga Slotted Steel Strap/plate (approx. $12 at local ACE Hardware)

- (2 to 4 sets) M8 x 16mm Hex Bolts, Flat washers, & "****" Lock nuts (a few $ at local ACE Hw)

----------------------- THE INSTALL --------------------------

01. Crimp & solder Male 9005/9006 connector pins on LED Light wires (install seals first!), then insert into correct pin cavities to match foglight harness.
ie Positive/Red wire = ORG/Wht wire (or YEL/Wht) on Mopar harness and Negative/Blk wire = Blk wire on Mopar Harness.

02. Seal up backside of connector cavities with RTV, even with back of connector shell. Set aside to cure/dry.

03. Cut the 4" strap to approximately 13-5/8" long & file rough edges

 

[Mpgrimm2]

04. Remove the (4) 10mm bolts from the backside of each of the existing tow hook blanks. Slide them out toward the middle of the bumper. Remove/retain (4) sets of the clip nuts and bolts from the blanks.

05. Temporarily install (2) clip nuts on each of the newly cut mounting plates as shown and install them using the original 10mm bolts. The plates will bend to shape once tightened down. Once done, remove, paint and let sit overnight.

06. Reinstall the painted mounting plates, and the LED Pods using one of the mounting holes/slots near the middle.
NOTE: you may have to push/bow in the middle of the mounting plate to get the needed recess/clearance for the lights.
