Good luck on this one. This is off a p model is which I think your chassis is. Check the red wire going to light switch then the tan wire going to fuse box. Then go from there. If this is a fiberglass body then check grounds as a lot of outside lights loose grounds. I might have other diagrams but not sure if for car or not. You should have three wires going to back yellow, green, brown. Brown will be taillights, yellow will be for turn sig green the same but I forget which side.
