I just recently bought a 1982 Brat that has a NON-working 3rd eye passing light. I was investigating the problem and found that the both the light and door open when hooked directly to a 12V source. After reinstalling the light in the grille, I did some research and located the relay under the hood. What I am missing however is the switch on the dash. There was clearly a switch there at some point, but it is no longer there. As far as I can tell right now, all I need to get this working is the switch. I looked up underneath the dash and found a 3 pronged female connector in the vicinity of where the switch should be. Can someone tell me if these are the correct wires? Does the original passing light switch have 3 terminals? Has anyone tried to connect a generic switch to it? Any information would be helpful. Thanks
