I connected my hot wire to the parking light button. I think it was a white wire with red stripe. but not sure. I hooked up the ground to a screw on the metal body behind the steering column. I think it was pretty much straight back behind the parking light button. So both my wires are in the same area. For the hot wire I tested with the lights on and/or parking light on and I took the red wire touched it to each wire on the back of the parking light buttom until my glow gauges lit up when the headlights were turned on or either when the parking light button was pushed. Then I just spliced it into that wire.
