If it's older then 2010, then I think it's just a matter of hooking them up. It is a factory option and we found all the wiring behind th dash to just plug them in on our 2007 379's. 2010 and newer, the lights are multi-plexed and controlled by the CECU. We added them to our 2012-2014 388's and the wiring was there, but we had to use Paccar ESA to activate the side turn signals in the CECU.
If your lights are multi-plexed, you'll need a dealer to activate them after you install them. If you try to jump the off the front or rear signals, the computer will sense added amperage and shut them down thinking there is a problem.
I have heard of people added them to the trailer circuit. That avoids needing to program the truck to accept them. Personally, I think it's better to hook them up just like factory though.
Edit: Look for the smaller bullet style LED's. The first set we put on with the normal 4" rounds and the driver complained that they were too bright in his face. We found smaller ones and the spot mirror blocks them from shining inside, but still visible front and rear from along side.TruckingTurtle, magoo68 and pushbroom Thank this. -

The left should be labeled J5, a yellow wire # 2311. The right is labeled J6, a yellow wire # 2312.Rusty970 Thanks this. -

I know this is an old thread but can anyone tell me what wires to look for on a 2012 389? Will they be there under the dash like the older trucks? -
