    Hey guys, I need all the wiring schematics that anyone can offer to me for the 98-02 LS1's. I would also like any wiring diagrams for an 88 truck, but i have a chiltons manual and can probably sipher through that for my truck. I guess i'd just really like some LS1 wiring diagrams. That's a million.

    The wireing changed on the f-body year to year so you might have to be more specific but I have some of the 2002.

    I don't know how to put it there. Maybe you can show me how and I'll get it to the reference section.
