I have an 86 GMC. Because of shift tube both ignition components and broken turn signal in the coloum I pick n pulled one from a 74. Starting, shifting is no longer a problem. Now it my lights and turn signals. I pull out the lights know. Everything is on. I switch turn left, left side goes dark. Same for right. No break lights or hazzards. No headlights as well. ground problem I think. But I am in no way an electrical expert. Other that pulling of the wiring bracket for the colum and trying all the combinations I do not know how to solve this one. Thanks In Advance.
