So I've finally got my 5.3 swap all bolted in and the modified (by me) GM wire harness /fuse box built and installed on the engine. Have all the pink wires (key on power) going to relays. What wire from the toyota has everyone been using to trigger relays and such for the engine?
Thanks to @rockrod’s chart I’ve got the Toyota harness stripped down to just the heavy gauge black/white stripe, the heavy gauge yellow/red stripe that goes to the fuse box, the t-case stuff, and water temp wire.
I plan on having the fuel pump wired stand-alone and it’s relay controlled by the wire from the GM PCM.
