Help tracing down a wire

[John Wooten]

I am looking for a place in the engine bay or behind the dash that I can tap into the reverse lights. Be even better if somebody new a reliable place to download the factory service manuals for wiring schematics.

Add a fuse in the fuse box in nice and clean. Non permanent way to do it. It's the only way I borrow signals anymore.

I'm actually adding an entire new fuse / relay box under the hood. The reason I need to tap the reverse light specifically is because I adding flood lights to the back and I want to relay them so that they turn on when the reverse lights come on, but I can flip a switch and turn them on when I need them.

This is pretty old - but some of the links may still be active

Could you tie into the factory 7-pin trailer harness for the back-up lights? That should be least invasive.

Well, your profile says you have a 2002, but you posted this in the 4th Gen section (2009-2018) so what generation of trucks are you looking for wiring diagrams on?

There are several sites with reliable wiring diagrams, but none of them are free.

Good video on the subject of getting wiring diagrams for almost any vehicle:
