Hello,
I have a wiring question for the pro's.
I have a wildcard box and a relay box with it. I am installing extra reverse lights under my bumper. I wanted to wire the extra lights to the reverse lights so they come on when I put the truck in reverse. I also want to wire the extra lights up so I could turn them off when I dont need the extra light to back up.
How do I go about doing this?
Thank you in advance.

Use two 30A Bosch relays.
Relay 1 - coil powered from the factory reverse lights, common to +12, normally open out to relay 2. This relay isolates the factory wiring and prevents blowing fuses.
Relay 2 - coil powered from the wildcard output. Relay 1 NO output to common input. Relay 2 NC output to aux reverse lights. Nothing on relay 2 NO output.
Reverse lights off - relay 1 common connected to NC, no current flows to relay 2. Aux lights off.
Reverse lights on, wildcard switch off - relay 1 common connected to NO, current flows to relay 2 common and out NC output to aux lights. Factory lights on, aux lights on.
Reverse lights on, wildcard switch on - relay 1 common connected to NO, current flows to relay 2 common connected to NO output (no further connection. Factory lights on, aux lights off.
Alternately, you put them on their own switch and turn them on manually. This is what I do.

Thank you for the reply. I had thought of doing the seperate switch but I will be using the lights alot when backing up and didnt want to turn them on everytime, I would only be turning them off a few times. This way I dont have to worry about hitting a switch all the time.
Thank you again,

No big deal. You might consider going a little further and having a button that allows you to force them on, regardless of the vehicle status. That way, you can use them for work lights (or bright-headlight dimmers )
I've got 4 600-series halogens (two Optiscenes, two spots) in my rear doors for backup lights. They are very nice to have.
