    This is the one i went and picked up eBay Motors: 2008 Chevy Tahoe 5.3L 2WD Engine Trans Street Rod LMG (item 370158861396 end time Feb-26-09 10:42:43 PST)
    it could be a 07' then? Will i still have to get the TAC module?
    if you look at this harness from Current it looks like they bypass the TAC module LS2/LS7 harnesses by Current Performance Wiring

    I just want this install to be ass easy as i can get it. Also off the subject, i can put a ls6 intake on with no prob also right? I just want it for clearance issues. The van is body dropped so i had to Z the front sub frame 5 1/2 inches so now the engine is that much higher.

    Thanks again for any help

    yea about the ls6 intake you will just need rail and injectors and the water pump there is a sticky on it and if its a 4l60 you can but if its a 6l90 your gona need the ecm and tac

    speartech and many others. There is a list of wire harness manufacturers on here somewhere. The search button is your friend.
