[QUOTE="SkySki Jason, post: 95956, member: 1118"] My harness will work for you, I have GPCM's in both trucks - they sent me the wrong harness when I was trying to diagnose another problem on my F350. I installed it for a minute to verify it was not a wiring issue and did not send it back because I 'used' it. Have you checked the grounds yet? Specifically the battery-to-block, but also the block to firewall and grounds from fuse blocks, etc to body. All of the grounds to body have PAINT on the body, so minor corrosion is all it takes to create a bad connection since it is just the threads making contact... There shouldn't be any reason ya can't remove and test your existing harness and find a problem, if there is one. I shouldn't be discouraging you from buying mine, since it has been resting on a shelf collecting dust for almost 2yrs now - but I'd hate for ya to throw money at a problem and not fix it (like I did!! :fustrate:). Sending you a PM. [/QUOTE]
