2002 Chevrolet Avalanche, Kenwood Excelon

New kenwood excelon installed on memorial day weekend 2023.mt onstar would not turn off, it was draining my battery, I pulled the onstar fuse problems solved. Now my windows, wipers, and sunroof will all work with the key off even after the driver's door is opened. I'm running the kenwood through the bose amp (which I hate) I have the pink wire from the amp to the blue trigger wire on kw I have the main power wire of the kw direct to the battery on a toggle switch the power wire is fused about 4 inches from the battery pos terminal. Why am I having these problems? My chimes all work and so do my courtesy lightsBluechevy

Hello, We were discussing it in my camp, did a little research- and found that the GMOS 11 Harness would most likely correct your symptoms. Best of Luck, I believe it's approx $120 on eBay, as they've been discontinued by Axxess from what I found. SPMista Pound
