zak,
took a little time out to give [MENTION=165]momo.75[/MENTION] some wiring advice and it would apply to you too.

or cut and paste of the same post for your refernce
Drop the driver side under dash.
On the bottom left of the fuse box you will see a red wire with a yellow trace. That is 12volt trigger for reverse light. It's in a 16 pin plug.
Several ways to do it. Get a double pole double throw relay
30 is power source
86 is 12 volt coming from reverse
87 is going out to the lights
85 is ground
That will give you a power source to rub the lights.
Now here is the fun stuff.
How to turn on with out turning on the reverse lights and back feeding power to the transmission! And possiblely messing up the trans?
Simple, two 3 amp does you buy from radio Shack. Yes that simple.
Here is a quick diagram i drew up using the diodes. Make sure the band on the diode is in the correct side. the band prevents power from flowing back into the other side back up into the reverse circiut in the car. Its simple once you grasp the concept of what a diode does. cool thing is if you flip the diodes around and use it in a negative circuit it will block ground from flowing back!
this page can help you understand diodes a little more

When the time comes for my reverse pods this is definitely the way to do it, thanks for sending it my way.
