Okay guys, I installed a truck side wiring on my 2016 chevy 2500HD Duramax and all I have left to do is bring the wires inside. I for the life of me cannot find a existing spot to bring this through. I already tried the cutting the nipple off the rubber gramet and coming in that way but seems like my harness is to big for that. Just wondering what you guys have done. Thanks for any input.
