Just the other day I noticed that my rear lights weren't working. I checked all the connections and it was secure, but I noticed the wires on the old harness were britle and crumbling on me when I tried to make a new conection. This is a 68 C30 rack body so it is not the real lights, they are just two round lights. I have the wires right: brown - power, yellow for left side and green for right; no backup lights installed. All the other lights up front work, but there is no juice to the rear. Any ideas? thanks
