Ok I believe I have the answer from question above. I have it wired and all the forscan stuff changed but not getting activation of hill descent. Any ideas.
I have 21 lariat non fx4 - rock crawl mode did show up.
So question. The first picture looks like you put the wire in the third hole from the left on the rear but the other picture seems to show the opposite and to place in the third hole from the left when plug is facing you. Which one is it.l
