Ok I got a problem. I have never had any problems with my 4wd. Well I just had a FPS go out on my truck. Well I put a new one in and at the same time I wired in my new circuit board from TST so the cool down timer will work on my tst and my buddy messed with the harness while I had the pins out and now I don't know if I have it all wired up backwords or what cause the cooldown won't work and now when I fired the truck back up I get a SERV 4WD light on my dash and my Lights above my 4wd **** aren't working.. WHAT THE HECK???? Help
