Hello, I was wondering if there was anyone here that knew these two questions...1. for back tail lights of a 1968 valiant, is there like a ground wire or somthing that might cause the lights to all of a sudden go out?....2. Does anyone know what wires go to what on the back tail lights, cause i think i may have re wired them wrong...if you can help please respond...thankyou  

well i dont know to much about 68 valients, but if you are stuck with no lights work from the lights backwards checking the wires for power and continuity. This happens to me at work all the time and is handy when you dont have a wiring diagram, but it is time consuming. check your tailight fuse. howe many wires are going into the harness for the tailights?

I have a 68 Valiant and had this happen to me, It was a bad wire in the fuse box. Dont know if this is your problem but it mite be worth a look. Hope this helps

Joe.
