So this time year in the rainy Seattle weather it is more difficult to see even without the limited visibility of the H3. I want to install some rear fog lights to make backing up in the dark easier to see. The hardware installation wouldn't be a problem but the wiring would be a hassle.

I was looking under the dash at the steering wheel and there are a whole bunch of (unattached) wires that look like they are used for the towing package. They are not connected and I am wondering if I could tap those wires to an on/off switch. Those wires should be attached back to the tow receiver where I could connect to the newly installed fog lights?

From the GM wiring schematics for the H3, the dark blue wire goes from the bundle under the I/P to the rear bundle for the trailer brake.
So, you could tap into the red wire (B+ through a 30Amp Fuse) at the I/P bundle attach this to one side of the switch, then attach the dark blue wire to the other side of the switch.
The rear fogs you can then power off the dark blue wire. For a ground, just attach to somewhere on the rear bumper should be good enough.

Thank you.

I finally got around to this install. I fabricated a thin piece of metal and drilled three holes in it. The middle hole goes through the factory bolt and the two others connect to the lights. I made the connectors to the lights quick disconnect in case I do some heavy off-roading. I don't want to rip them off.

They don't really decrease the approach angle but you never know. Thanks again f5fstop for the wiring information.

- I installed these rear lights...

You really need to wash that H3 Hummer.
It looks like mine after hurricaine Wilma hit it.

yeah it is dirty but it will rain until march around here so i can't justify it.


Green Lantern I noticed the CB radio antennas can you let me know how you installed these? Or take a picture? I have a tall off - road flag I want to install to the base of the spare tire but would like to see some pics. if possible.
