Just wanted to let people with the earlier 4th gens (2010-2012) like myself know that MPgrimm2's foglight jumper harness will in fact work on our trucks as well. I recently contacted Mpgrimm2 about getting one of his jumpers after I heard about him from Greg A's YouTube channel.
I had already gathered up all the necessary parts to add the factory fogs to my truck and just needed that final piece he provided to finish the puzzle. Parts needed to complete the install below.
Obviously you'll need a bumper and foglights which I found on craigslist for fairly cheap off a 2011 Ram 2500 Power Wagon.
The foglight harness I found on amazon surprisingly.

The correct headlight knob with the foglight button in the center of the dial, also on amazon.

The fog light jumper harness I got from MPgrimm2.
He was able to get me out a jumper harness for my truck and I've already done the install with everything working great!
Most of the steps he's detailed out above in the original posts are basically the same for our trucks with the only real exception probably being the wiring locations in the harness for our TIPM Box.
He was able to provide me with the correct illustrations to A) Find the right harness to use on the TIPM B) The correct locations on the plug to place the added pins from the harness I got from him C) Hook up the ground wire for the foglights.
1.To start this project, I would recommend removing the grill and the drivers side headlight.
You only need to remove the four nuts (18MM Deep socket or wrench) on each side holding the bumper to the brackets. Two (one on each side) of them on the top are really only accessible from the top of the bumper which is why I removed the grill.
2. Once I removed the bumper and took the headlight out, I next took the Jumper Harness and hooked it into the correct harness on the TIPM. I ran the harness out the open side of the TIPM box toward the inner fender, then routed the jumper wire down the frame like shown in MPgrimm2's posts using the provided zip tie plugs to tie it in place on the frame.
3.Before bolting the new fog light bumper with fog lights already installed in it to the truck, I ran the factory fog light wiring 68046303AC inside the bumper and got it all in place. Once I had all the wires in place and tied in neatly, I bolted the bumper up to the truck and got it positioned evenly, then reinstalled my headlight and grill.
4. Next I swapped out the headlight knobs. Super simple process as shown above in the previous posts.
5. Rather than take my truck to the dealer and paying them to flash the computer, I opted to go the AlphaOBD route as I plan on doing more additions down the road. If you plan on only adding the fog lights, it'd probably be cheaper to have the dealership flash the computer instead of paying for the Alphaobd app on the google play store, buying the OBD adapter, and in my case purchasing an android tablet to use the app on because I'm an apple guy. It was as simple as changing the fog lights from not set to set in the computer of my truck though and now I have functioning factory fog lights.
I'm super happy I did this upgrade to my truck. When I first purchased my truck, the halogen headlight bulbs in my SLT headlights were terrible in the dark. You could barely see anything. I've since upgraded to LED bulbs which are so much better than the halogen bulbs, but now that I've added the foglight option its awesome. I can see so much more in front of me on those dark back roads now.
Sorry if any of this was already covered in previous posts.
Thank you MPgrimm2 and M2 MODS!
