LED Light Bar

[James Petrik]

I am installing and LED Light Bar I in my last truck I had a seperate reverse light wire to splice into. What color is the reverse light wire? i know how to remove the light I just want to get the correct wire without playing a gussing game.
Thanks
James

As far as I remember, it was either blue or red. I think it was red, but I am not sure...

It will be the blue wire.

Etrailer has two versions, here's a third. Best to test.
