View Full Version : LLY: Harness, fusebox under hood

I wondered if someone have, or know were I can get a instruction over each wire into the fusebox under hood in a orginal harness on a lly engine? I have put a LLY engine in a 1989 silverado. And need to know what wire that goes were.. :(
Here in Norway, at the chevrolet stores they say they don't have instruction or a diagram that shows what wire that goes were.

Your best bet would be to get the GM service manual on CD and look up the wiring diagrams. Not a cheap option, but the CD covers ALL GM vehicles from way back to now.

Be careful, when I got mine it only worked on XP machines, NOT Win7 or Win7 XP emulator. That may have changed since I bought mine.

Good Luck.:thumb:
