Does anyone know which wire is which on the original running light? I have Tone's shop manual, but can't seem to find it. If you know which wire is which, or where to find it in the manual, I would greatly appreciate it.
Mark,

Yes, LEDs (in the angel eye rings) need to have correct polarity.
But you don't need a manual to figure out what wire is positive and what is negative. Even if you do have one, it's always best to physically test the wire polarity.

The best way to figure it out is to use a circuit tester and ground to the car frame. A simple one that lights up or a voltage tester will work (set on 20V DC). Connect the black wire of the tester to the frame, and poke the red wire to the fog light wires, which ever one lights up the tester - that's your (+) wire. If you're not getting a voltage, you may have to find a better ground on a bare metal bolt or another spot on your frame... good luck.

BTW, I probably have the same fogs with angel eyes, just waiting for some time to install em. I also plan to wire the two (ring and light) separately with a relay and switch. If that interests you, I can help you with that kind of wiring too.

P.S. Biju and I expect at least 5 more mods from you by next Moab .
