So I might have gone a little to dark on my window tint and I cant see Sh@t backing up, So I bought a pair of Vision X Solstice LED lights to light the way, They dont draw much currant so I can Tap into the factory back up lights to power them, My Question is which wire is the hot on the factory harness going to the back up lights. I loaned out my voltage meter so now Im screwed.I am assuming it is the grey w/ purple strip. Seeing the other is black with green stripe. Any help would be greatly appreciated.

 

I just use one of those Blazer? plug in flood lamps that stick in teh 7 way connector. No mess or wiring and it works awesome. $20 bucks at Lowes here.
