Years ago I rewired my fuse Box and ECM under the bumper of my truck. Now I need to move it all for the twin Turbo intercooler. Biggest problem is German shepherd pups broke into my garage and chewed through a bunch of the harness so I have quite the mess to deal with. My truck is officially just a toy and I figure there has to be a bunch of useless wiring I can remove while I'm redoing all this again. Does anyone have any sources or ideas of how I can strip this harness down to the bare necessities truck does need to be street legal. A full and complete wiring diagram would be nice but I have found nothing complete enough for me to start pulling wires confidently. Any ideas or help will be appreciated. Thanks

 

I assume this is the truck in your sig?

This should give you the path to success

 

yes it's the truck from my signature. Thanks for the link I'll look it over after work.

 

LT1 swap is the goddamn best. Check out his YouTube page too, theres a trio of videos where he goes over an ENTIRE harness, super helpful.

 

When I did my build I ran into the same issue. My solution.....I tore out every single strand of wire and rewired the truck myself from bumper to bumper in a "modular" fasher. I made a harness solely dedicated to the chassis (lights,windows and things like that. Module two was for the efi system.
By the way, I've done several other trucks both drag and street using the same method. Looks slick as hell, trouble shooting easy, and simple to operate. I don it a side hustle. If you or anyone else is interested...hit me up for a quote.

 

I would be interested in a quote. Are you able to accomplish this without the truck? Seems like it may be difficult. Can you send me basic pics of how your truck wiring looks? Thanks

 

This is a project i'm going to start myself soon but would be interested in paying someone. Send me a p m with some details. Thanks.

 

I have actually done several of what you are talking about. I'd be interested in discussing. Check your pm's.

 

Did you get my pm
