Well I wired my reverse light switch, getting good power and ground because the LED on the switch comes on, but it doesn't turn on the lights. I wired it to the Reverse light wire going to the relay.
Also, my trans temp gauge seems to be working, magically
, but a little issue. I stole power from the 12V switched wire from the radio [which works exactly as it should], but the trans temp gauge power plug is getting full-time power. Any ideas? 
Anyway, pics

You must have wired it to the wrong wire. there is a constant and a switched to the radio. If there is power to the gauge when the ignition is off. You have the constant. Use your voltmeter, check if theres 12 at it when key is on or off or all the time.
So far so good. Mounting was simple, took it up on some forest roads today and just pulled it up a slight hill worked good, then there was a fallen tree on one of the trails so I pulled the tree off the road with it and had no problems.

Gah that would suck because I soldered it in. Oh well, I'll check it. Any idea on why the reverse light aux switch doesn't work? Power to the switch, but it doesn't turn the lights on.
