I need to wire in a "4 prong harness" to my 1999 JEEP Grand Cherokee. I know I need to attach the brown wire to the tail light, the green to the right turn light and the yellow to the left turn light; my question is what is the best way to do it and where should I acces those wires in my tow vehicle (JEEP).
I pulled off the right rear tailight, but I don't recognize the color coding.
