Electric rear window switch question

[Peter Coomaraswamy]

I'm helping a friend re-assemble the interior of his '70 2800CS and the rear electric windows have three wires each side. My question is; does this take a special switch with three connectors or do I use a 4-prong switch and just leave one open?

Thanks,

..does this take a special switch with three connectors or do I use a 4-prong switch and just leave one open?

I am 99.9% certain that it's the latter; e.g., use a 4-prong switch and just leave one open.

Next you're going to ask which wire goes to which terminal.

3 terminals of the 4 and I think the black goes on one side and the greens on the other, then see which way you push the switch to open/close and install back into the arm rest accordingly

Cool, Thanks. The rear was disassembled by the paint shop and things not marked very well.
