Niff,
Which wiring harness did you use? Info and part numbers on 1t page are not posted anymore. Having some electrical short issues. Funky stuff, noticed a spark on the brake vacuum booster at the inside bolt which gets hot and the brake lines also. Wondering if the harness I got is the wrong one for my 07 Avalanche that came with 5.3 FF engine.
