Back up light - The 1947 - Present Chevrolet & GMC Truck Message Board Network

79gmcc15 · 12-21-2010, 04:04 AM

Hey, so my back up lighting situation SUCKS! Ive offend thought about getting a cheep pair of driving lights and hooking one up to my trailer hitch. So that when I put it in R it lights up better. Then I remembered I have a old one that was on the front of the truck when I got it. I never figured out how to turn them on *no switches in cab

*. So how do I go about hooking it up to work like I want?

You would need to run driving lights though a relay because the wiring from the factory will not support Driving lights , at least not very long.

The normal back up lights in a square body are run thru a light green wire IIRC .yellow =left turn....dark green=right turn....brown=tail lights ,.....black is ground.....light green= reverse lights.

the light green wire runs to the neutral safety switch/backup light switch , low on the steering column

That's what I did, I just have a switch in the dash that I flip when backing up. They are also nice when trying to back down a boat ramp at 0 dark thirty in the morning. (and occasionally letting tailgaters know I'm not happy about them being so close

)

Thanks guys for moving it.

On second thought, would it be easier to just hook it up like Augie? I guess I don't need it every time I back up.
