Wiring differnences in SA/FB S1/S2/S3 power window switches - Hardcore Tech with Pics

[2gslse]

Ack! I've been chasing an INOP passenger power window since I got my 83 RX-7 GSL (S2). By popping the center console panel and swapping connectors real quick I was able to determine that the window operated perfectly (by using the driver's side switch), it was simply the switch that was bad. The problem with this is that switches are over $100 each new and the used market is rather "thin".

I managed to obtain a few spare switches. The first is a S3 (84-85) switch assembly. The S3 uses a different style of switch, there's still 2 rocker switches (one for each window), but the plug into a single harness. This assembly may operate S1/S2 windows, but one would have to sacrifice 2 S1/S2 switch harnesses and a S3 car harness to splice in a mid-harness, which seems like an awful lot of work.

I also obtained a set of S1 (79-80) switches. The rockers themselves are identical to the S2 rockers, down to the part #. The harness is even the same. However the harness features a different wiring scheme (solid green and green/blue chaser for the S1 vs. solid green and black/blue chaser for the S2). The harness itself also connects differently to the back of the switch. I believe that these switches can be re-pinned easily to work with the S2 car harness as one switch will roll the window down, and the other will roll it up.

More to follow!
