[QUOTE="13fist, post: 1533035, member: 31010"] Yeah so it's decided to rain all day. Progress isn't what I had hoped for, but Managed to get a lot done anyway. Pretty much all that's left is ICP & IPR pigtails, then organizing and wrapping things up. Probably Monday before I get to it again. I did plug everything back in an take it for a drive to make sure I hadn't messed anything up. Luckily no smoke, sparks, fires, or check engine light. I must insist on a measure of leniency for the following images. Weather and needing this running for tomorrow, everything is temporary. Better details and pics will come.... [ATTACH=full]177568[/ATTACH] Huge mess right now :shocked: LOL. This is a completely unwrapped wiring harness with everything separated. Don't worry, it's not staying like this. This is the good stuff though, [ATTACH=full]177569[/ATTACH] 2ga cable to alternator, 2ga buttsplice with the gpcm connection crammed in and chock full of solder. Wrapped in adhesive heat shrink tubing. I'm still somewhat amazed the number of discussions I've read stating this cannot be done. Surely I can't be the first 7.3 guy to go there. [ATTACH=full]177570[/ATTACH] 2ga cable runs along above the valve cover to the alt, then back down the the driver side battery. [ATTACH=full]177571[/ATTACH] protected by 250amp mega fuse. Although not originally planned this way, I do like the fuse location. Might make this permanent. Over on the passenger side, I just ran the wire from the solenoid to the battery terminal over there. AIH relay, bowl heater, water in fuel, and a slew of other things no longer on my truck got de pinned from the 42 pin connector. I never liked having the wires flopping around for nothing. Over all this is not hard to do. Just very time consuming doing one wire at a time, checking continuity & resistance, and making sure nothing get tangled or spliced to the wrong thing. A good heat gun, soldering iron, smallish butane or propane torch, and top shelf wire strippers are about all of whats needed for tooling. More to come. [/QUOTE]
