Okay so I know this question has been asked a million times. I have searched and read many of the past threads and none of them really answered my ? . I want to add some lights to the rear, and front eventually too. I need to know where I should add the relay. To the 7 pin plug or can I add it to the switch in the cab for the running lights. I want to be able to turn the lights on when not in reverse, but at the same time I don't want them to be on when the truck is off (just in case). Any diagrams would be awsome. Thanks for the help guys.

 

I have the PIAA backup lights installed but I did not hook up the wire that makes them go on when tranny is in reverse.

I'd love to know where I can tap into that wire somewhere in the dash area.

 

i installed a set of kc back up lights. everything came in the kit. the relay, the toggle switch. they turn on when in reverse or i can flip the toggle switch manually and the lights come on

 

i was lazy and just bought the white knight system from geno's. they work great for me.

 

This is what I did for $20. Wired them straight to the battery and put the switch where the adjustable pedal switch would be if I had them.

 

Where are you guys wireing your relay to?

 

Me, I'd create my own circuit for the lights. I'd tap into an underhood battery source, like the stud on the PDC, run a fused line to the relay, mount the relay either underhood or underdash, use a lighted switch to control the relay at key-on only, and run the output wire to the rear of the truck.

 

Here's a schematic if you want to wire it to a three way switch so they'll come on automatically with the reverse lights, come on manually, or stay off all the time:

 

Can I run the relay to any circuit? I would like to attach it to one of the wires for the parking lamps so that I can turn my lights on any time that the parking lamps are on, and won't stay on once I turn off the truck.

 

How about tapping into the 7 pin loom for the trailer? You can get both a power signal from the back up and the constant hot from there. At the same time, get your truck flashed for the TSB about the trailer circuit problem.
