You talking about these guys: Hummer H3 Off Road Lamps Switch 88963884 Connector 12101864

"The switches for the off-road lamps are located in the center of the instrument panel below climate controls.
One switch is used for the front lower-grille mounted off-road lamps, if equipped, and the other switch is used
for the roof-mounted off-road lamps, if equipped."

The switch is actually 2 pieces. The switch and a connector (pigtail harness).
The switch comes with no documentation, but if you look close on the back of the switch you will see
the markings A, B, and C for the respective pins.

A: GND
B: Accessory
C:+ 12v

Note: I see A and C swapped in quite a few posts across several forums.......Installer beware.....

This is a quote from Gunner45 in this thread. OEM FACTORY LIGHT SWITCH ; and have a look at these too: RE: Aux Switches

I posted this on HJ's light bar thread initially, but thought it pertinent enough to post here as well....

(Just something to consider when planning your lighting set-up.......Gunner_45)

============================================================

Does anyone know what the alternator for the H3 is rated at?

Also, does this equation fly for calculating amp draw for lights?

Light wattage / Voltage = Amps

So...in my case, if I wanted 4 KC's on the roof and 2 on the bumper:

130w / 12v = 10.8 amps

6 (lights) X 10.8 amps = 64.8 amp load on the system with all lights working.

For me, on my last project truck, that was the ideal setup. However, I ended
up putting a hi-output alternator and dual 900cca batteries on the truck with
an isolator......That was a huge draw on the stock 90 amp alternator....hence the mods.

Just some food for thought.....

Comments, corrections, suggestions.....?????
