hey i am wiring up a fading neon licence plate frame right now and the directions are telling me to:

"wire in the white wire to the brake light and the black to a ground."

well i crawled up in my trunk and poped off the 3rd brake light bar wire thingy.

(man this must kinda scare some of you when i say "wire thingy")

sorry its a connecter, the male end. there are four wires coming out off it and i am tring to find the brake power source. they are colored as this (let me run out side and see)..............................


(door slam)

(door opens)


they are as ordered: green with orange strip, solid black, solid green, black with white strip.

so which should i tie my white wire to the brake light too and which to the ground?

remember its fading and i have to find the brake wire so it will be steady on while i brake.

i guess green is always ground right?

DC
turn it to the 20 volt setting and turn on your lights. Look for the combination that shows 12 volts. then have someone step on the brake. if the voltage shoots up it will get brighter. Heres a better idea, use the wires for the liscense plate lights. theres a constant voltage and only 2 wires, also less distance to run new wires

Neon license plate frame?


If you want to use the 3rd brake light harness, there should be one ground wire and one wire that is hot with brakes. If there are others, they may be there if you want to add a trailer harness (turn signals). One of the wires should show continuity with the chassis (that's your ground), and one should show +12V when the brakes are applied.
