We've been working on a 70 GT for about two years now...not on the road yet. The PO had re-wired the headlights using a toggle switch and they did work when we first got the car but they no longer work.
I have attempted to add a new toggle switch following the instructions from the OMC site.....running from the switch to the fuse box and from the switch directly to the headlight relay. I get a clicking sound from the relay when I flip the switch but still not lights.
From this brief diagnosis....do you thing I have a bad relay or the fact that it is clicking mean that it is good???
