No, it’s not 28… I sold the Hummer last week. I think the fuse was 33 or 30-something, it was labled accessory…

The slot with the 15 amp fuse where your wire was ran on the cover was labeled as #28 BCK/UP? is that what your calling the accessory? Just don’t want to short circuit anything, just to be certain, besides that great video!

Like you, I have a 2006 Hummer H3. The wiring harness was found on Ebay for 4 bucks model number GM-4004. But you can just do a search for the wiring harness for your make and model. It is a basic harness to your speakers. There is a more advanced harness that will cost well over a hundred. I hooks into your On-Star and will cause the speakers to “chime” and keep everything in the car on until you open the door…

Well, it’s not so much that… (Stereo is free, n I can always replace it if I’m alive.) I have the Hummer garaged now and is being more discreet… (Watching where I go and how long I stay.) I used my other truck for transportation. Next time this 2-way pager alarm goes off, I got something for that ass. I know people are struggling out here, but I have to make an example… It’s a respect thing… ^_O

I’m not gonna pick on you to much here but why in hell did you not use any “crimps” black electrical tape does not fix everything! Not to mention how easy it would be to jack your stereo! Other than that the info isnt so bad
