Have you figured this out? Your wire colors match the 71 USA Diagram and they seem to function differently than a 72-73 car like mine.
The red wires coming into the switch have batt voltage from fuse 11. (Check with a voltmeter. Have a good fuse installed.) The other red wires provide voltage to the buzzer as far as I can tell. They should be across one set of switch contacts. (I believe the buzzer gets ground through the ignition switch.) The brown wires should share the other switch contacts, and provide ground for the dome light. You'll have to check the switch and see which pair of terminals connect when you actuate the switch. I tried checking how the wires go on my door switches, but I couldn't get them out without a fight. I think they're different anyway. Let me know how this goes. I'm curious.

(IMG:style_emoticons/default/smile.gif) Not yet. This is what I have figured out so far: 1. The wires from the door switches are connected from left to right (so no broken wires). 2. There is power from one of each of the red wire groups on either side. So one set of red wires does not seem to have power. 3. The grounds (brown) wires are connected to the dome light on the driver side. 4. I have continuity on one set of leads on the switches from front to back with the button out, but not in. The other set of leads don't seem to have continuity either way. I cleaned one of the switches with Simple Green to see if that helped. It did a little. I need to check the buzzer to see if it's even installed. I hesitate just because the relay board has so much stuff on it, it's old and I'm afraid of breaking/cracking/shorting out anything and it's a pain to deal with. I may just figure out a way to just get the dome light working, or just tape off the leads and put the switches back and leave them un-hooked. I don't really need a dome light. |
