Hello, I'll have my h3 on Tuesday and I was just wondering if the electrical connections on the h3 is the same as any other gm model.

I'm planning on installing an alarm, probably another Viper 791XV and I'd rather not tear up all the wiring on the new truck right away. So I'm thinking about using a t-harness for the moment.

This site has the most t-harnesses I've seen, doesn't list hummer under any of them though. Anyone know if there is one that is interchangeable with the h3 on there or a place that sells h3 t-harnesses?

Also, anyone happen to have a wiring diagram for the h3 handy? Thanks
