I'm making some headway with the wiring in the Diamond T. (Well, I THINK it's progress, we'll see when I try to fire that bad boy up!) I've got the underhood fuse panel from the donor Silverado mounted, who's job it is to fuse and organize the engine/ECM. I thought I could use the other circuits for everything else, but way these things are set up doesn't lend itself well to backyard cobbling. Loosely translated, that means I couldn't figure out how to do it, even with schematics and pin-out charts.
