Hello guys

I just spend some time this aferternoon to put aux lights reverse (2 lights 55w each).

After read some post about that mod. I decided to tap my lights on the 7 pin trailer socket.

I used the wires grey (positive) and white (ground) . I didnt put swicht on\off and I didnt put realy.

I just want these lights bright when i am on reverse only.

Now it is not working at all ????

Do you have any ideas what I did wrong ????

I am so mad after spend a lot of time on that !!!

Tanks a lot to helping me !!!

 

when I did mine I grounded my lights to the bumper. The lead for my reverse lights is the middle wire in the 7 pin. Not sure on the color of the wire. Hope that helps. I love my aux back up lights. I used Maxxima led lights and it was the best 60 dollars I spent on my truck.

 

You might have put lights that draw too much current

 

I would think you need positive, negative, and ground. Not sure though.

 

???

 

Yeah it's not a good idea to add 110 watts to that circuit.

I would use the existing reverse light to trip a relay and put the added lights on their own circuit.

 

^ What he said.

I have 2 x 55w halogens. Based on the experiences of others on this forum, I get power from the reverse wire in the 7-pin trailer socket, use a relay to trip my lights and have a 15A fuse in between my stuff and the rest of the truck's wiring, just in case. I have the lights grounded to their own mount and the bumper.

The lights didn't work at first and it turned out that the problem was bad grounds. Paint on the screws was insulating the ground wire. Once I filed off the paint and got to bare metal, all was good. Covered everything in liquid e-tape.

 

Did you install the fuse and relay that you got with the truck?
On mine i had to install a relay and fuse, and it was for trailer towing, but not quite sure if its for the 7 pin plug or what its for exactly.

 

The relay came with the lights. I installed an inline waterproof ato-type fuse holder and 15A blade fuse that I bought at Autozone.

 

How about if you just threw on some Rally LEDs and hooked them to the center pin and self grounded? Being low draw, would a relay and fuse still be needed? May be easier and provide enough function without all the hassle.
