EDIT: This is a 91 chevy s10 blazer, 2dr, 4wd, 4.3ltr z vin.

I am installing a 4 flat trailer light plug. I either need a wiring diagram for the tail lights or help on which colors to attach to. (The right side says green wire, but there are 2 green wires, one dark and one lime) The left says the yellow, and there is luckily just one yellow. White is ground (figured I would just ground to the frame, but there is a pre-existing white wire in the bunch) If anyone can help me on this, it would be great!


Thanks
Steve

 

Basically you just match up the colors, yellow to yellow, dark green to dark green, and the white in the bunch is a ground wire as well. so you can use it or just ground to the truck.

 

Green = right turn / brake light
Yellow = left turn / brake light
Brown = tail / running lights
White = ground

As you look at the flat four wire harness the colors should be Green/Yellow/Brown/White in that order.
