How hard is it to wire in extra lights such as marker lights with your running lights?? I'd like to put ambers on the sides of my toolbox, several brake lights along the back of it, three ambers in the grille, along with the candlesticks have for the bumper

not hard, you either run a wire (fused) from the battery to a switch, and from their to all of your lights. If you want them tied in to your running lights from the factory switch, you need to tap into the wire somewhere maybe someone else can help you locate it.

 

You can tie in to your brake light wiring at the lights on the back of the cab at the top, or by the rear bumper up underneath. Again not sure on which wire is is exactly, in the rear 2 are for turn, one for brake, and a ground I believe.

 

I know that your front left signal is the green wire, brown is running light, and black is ground. Black should be universally ground on the whole truck. I'm guessing ford didn't change the wire colors in the harnesses between years, I'm going off my 91, which I've added over 50 extra lights to.... So I'm becoming familiar with the wires lol. I have not tapped into the rear lights, but I would guess that green would still be left signal, and brown running lights.

 

I just ran off of my trailer pigtail. Tapped into it behind the bumper and ran my brake and turns for my cab guard. That way I did not have to jack with the factory wiring.

 

What color does what on those?

 

More info please lol I like this approach because I don't like screwing around with stuff
