    Was looking under my hood trying to figure out where to wire my new lights through. Looked at running it through the fire wall where all the other wires are entering into the car. However, the wires are taped tightly together with electrical tape and its impossible to squeeze the wire through...

    Hey everyone, I have a semi-major issue. This evening, I hooked up two reverse facing fog lights, powered by the 12v power source in the rear of my TB from the cigarette lighter receptacle. This worked great because I had it powered through a fuse, which connected to an on/off switch provided...

    I've had my Trailbazer for a few months and in my opinion it's definitely the best vehicle I've driven. I really enjoy my music but don't really have much money to spend on an after-market system. I figured that I could start with a fairly decent sub but I really didn't want to spend more than...

    Although I thought I'd be able to add this to an existing thread, but none appear to be quite the same - I'd be hijacking someone else's thread instead of adding useful info - so here goes with a new thread. Hopefully this will be useful to someone else down the road. 2004 GMC Envoy XUV with...
