Hey guys,

Quick question....i just bought the fire and ice light bar. thing is sick but i need to know which wire on the tailight harness is the wire for the backup light> If you are familiar, each of the 3 bulbs dont have a wire to it but they are all connected to a 5 pin harness. One of the wires i blieve is the Ground (black). All the otheres are wierd color combo wires. nonetheless idk which one is for the back up's.

Inputs please>>>

 

The fire and ice bar (plasmaglow) i put on my 2006 came with a 4 pin trailer harness along with a separate white wire which ran the back up lights. I didn't want to cut into the truck wiring so i picked up a 7 pin trailer connector and spliced the wiring from the bar onto the 7 pin connector.
On mine the reverse lights connect up to the center pin of the 7 pin harness...

Good luck with your bar, they're sweet...
