Trailer wiring is a pretty easy thing to install and the T-One connector promises to make it even easier by plugging into your factory wiring harness to eliminate any cutting and splicing. Despite the install instructions, the 2006 Hummer H3 w/o tow package, does not have a harness to plugin to. There is a bundle of wire leads that are capped off right behind the rear bumper. You must cut off the nice "T" connector and splice directly into these wires. So, if you have an '06 H3 you'll be better off just buying a simple universal splice-in harness.
