wiring rear light bar

I just bought the light bar that goes under the tailgate of drw SD's!
The question I have is it has a plug on the end of the wiring harness and I dont see a place in my harness to hook it into? I have a 02 250 cc sb srw 4+4. I assume I have a different wiring harness than drw have. If so,I will have to cut the plug off the end of harness and splice into another wire,has anyone done this and where would be the best place to splice into?
Thanks in advance,

Dont know which light bar you got, but the two wires should be a ground and a power wire. You will have to cut the plug. Assume white is a ground. I dont know what color wires you have. But ground one wire and the other wire should go to a brown colored wire in the loom of wires in the back. Brown is the parking light wire. Hook it up and test it. Should work. Good luck.

wiring rear light bar

I bought the light bar at a tractor trailer garage that we get work done at. So mine didnt have any plug on it. I just grounded the one wire to one of the mounting bolts and spliced the other into the licenes plate light harness. It was quick and easy to get at. If you look at the plug that goes into the light and there are 2 terminals in the plug it doesent really matter which wire is grounded and which is the hot.(thats if they are a sealed marker light like we use on the big trucks.)

wiring rear light bar

I had a similiar question............

I bought the LED style light bar from AW Direct. It gives you a harness that plugs into all three lights.

This is my first time messing with LED's. There are two female outlets on each light. As long as I do them all the same (1 color ground, 1 color positive) does it matter which outlet on the light itself gets power or ground?

OK so I have been saving up for some dumb questions. We do you get these light bars and how much do they cost? Where are you putting them (on the tailgate or below between the bumper and the gate)? What is the difference between LED's and regular lights? What are the PN's you guys ordered??

Thanks,

CBSD

wiring rear light bar

CBSD: The light bar I have is the ford part(#FS1Z-15444-AA),it is the same one that you see on the duallys. It is mounted right under the tailgate,if you look at yours you will see the holes are already in the metal! I could'nt see where ford would make a separate harness for each vehicle as the bed's are basically the same. I figured I could bolt it on and plug it in and go.But could not find plug so I will take the advice from thread and cut and splice.
Thanks for the help,SC

I have a cheapo LED flashlight. I was messing with it one day and found that the positive/negative power supply orientation DOES matter. It worked one way. It didn’t work the other way. I don't think applying power "backwards" does any harm though. Thinking some more (this is where it can get dangerous) it makes sense, since LED is Light Emitting Diode - diodes only transmit current in one direction.
