FICM issue

Hey everyone. I just installed ARP's in my friend's '03 and when I had it apart I noticed 2 pins in the front most plug socket of the FICM looked like they had burnt up. I ran a small screw driver up and down each of those pins to clean them up but I never bothered to look at the plug! Well I should have because he now will only start when the truck is plugged in. I checked the FICM voltage and got 36v with the glow plug control module unplugged. Pulled the FICM and it has a build date of 1/21/10 however I think it's just a replacement case half. Here's one of my problems, when you split the case there are the 4 stantions that come out from the computer PCB and I would assume pass power through to the DC-DC converter. The 4 screws accessible through the little cover (and the same screws you use to test voltage) screw down into these stantions. Problem 1 is one of these is stripped and it looks like it's been this way for awhile. I can't tighten the damn thing and I can't get it out either, leaving me unable to remove the PCB to solder! Second problem is that harness is toast. I'm just wondering if I HAVE to get an 03-04.5 harness or if I can just lengthen an 04.5-07 to reach the rear ICP location on this '03. This would be too easy but doesn't anyone know if there's a relacement plug available? I'll spend the time re-pinning connections over replacing that whole harness!
