Am a very satisfied Limey having just received my truck.Unfortunately our meddling suits require the rear lights to be changed and in doing have removed the backup lights.What color in the loom are these?

 

Hello Philby,
Can you give us a bit more info about your truck?
Year and model would be helpful.

Your best bet for something like this is to buy a Haynes or Chilton manual for the truck. You can get them from specialist suppliers in the UK like Millhouse Books.
Have a look at the adverts in Classic American magazine.

 

The truck listed is a SuperCrew XLT, or it is at least a 2001 ( or is that 2000 ?? ).

The reverse lamps in the wiring harness up by the tail lamp is Black with a pink stripe on the pos side ( the side from the reversing lamps switch ), and the neg side is the black wire.

If you have a factory trailer adapter, with the relay in place, in front of the round 7 pin adapter it is a black with a light green stripe on the pos side ( from the trailer tow reversing lamp relay ).

Either of these will work getting a set of reversing lamps to work. If you are using a wattage blub higher then the 21 watt bulb ( think that it is what they are stock ? ) use the trailer connector for powering it, or a relay feed from the battery, and the normal harness reversing lamp lead.

Good luck, let us know if you need something else on the topic.

 

I added aux. back up lights. I used small 55w fogs and mounted them on the receiver hitch using the mount brackets and large hose clamps. I wired them to the tow plug. I think it was the center pin. they come on when put in reverse. I didn't feel like running a wire and adding a switch in the cab. they have been on 2 years with no problems.
