I'm planning out the wiring in my 73 El Camino
I'm going total custom wiring, most of the factory wiring is being pulled because they previous owners hack jobs.
I have the window switches in question, I believe they are rated at 20 amps.
The wire color maybe any color they have at the time they make the plug, so the terminal position is the most important aspect.
However if you have a Brevet ER.GI window switch that many of us have from some of the retailers, the position of the terminals is the key because of the internal wiring of the switch, see the screenshot.
A + B are the power for the switch
C + L are the power for the illumination
D + E are to the wires to the motor
Some of the wires can be connected in parallel like the power, ground and illumination, with barrier strips
The internals of the switch alternate the positive and negative to the motor, switch them as needed to make your windows go up to your switches position.
If you goggle - Brevet EG.GI window switch - you should find the PDF file that i took the screenshot from.
I don't recall the person that did the second to the last post, prior to this one but he's on it, and you can make your own switches with any high amperage DPDT switch, just don't hold the switch in the on position for long periods of time after the window is at its limits of travel, that will heat the internals of the switch up and melt the contacts in the switch.
