2000 SC1
Default Today's Mystery Connector

You'll love this.

For years I have seen this connector, tyrapped near the radiator on the passenger side of my SC. I never really looked too close at it, everything works fine on the car, no mystery codes, etc. Without giving it much thought, I assumed it was an unused connector for fog lamps or something.

Today I was cleaning my EGR, general spring maintenance and decided to look closer. It only has 1 green wire in it, so obviously cannot be for foglamps, plus looking closer at the connector it looks more like something for a sensor of some sort. There is nothing nearby that looks like it is missing a connection. The location and clip mount indicates the connection must in the vicinity but nothing is obviously unplugged. Like I said, everything works fine, I do not know if it has been tyrapped there from the factory (doubt it) or whether the PO did it back in the day.

Any ideas?

Thanks

Without a better look at it, I'd guess it goes to the AC compressor if you had one, but Gen 3....isn't there some kind of air valve on the Gen 3 right around that right front side of the SOHC engine?

Default Re: Today's Mystery Connector

Dunno about an air valve, but you could be right about an AC connector, it would make sense. Since I don't have AC I just would have thought it would be wrapped out of the way better if it was a redundant connector from the factory.

Does anyone have a wiring diagram that shows the color code for an AC connector?

Your car uses a single dark green power wire to the a/c compressor. One way to verify this connector as the power wire would be measuring it for 12 volts when; locating the a/c relay and removing it (if one exists), familiarizing yourself to relay pinouts, inserting a small wire jumper across relay socket terminals 30 and 87 - sending fused a/c power to the compressor. A fuse and relay would have to be in place in the engine fuse box. Another way would be a continuity test between this connector and either terminal 30 or 87 (the a/c fuse should be removed to prevent sending 12v into a meter set for resistance/continuity testing.

I found a wiring diagram from you fdryer on another thread - it does look like the AC compressor connector. I'll verify continuity with terminals 30 and 87 this weekend, but I think this may be mystery solved

Thanks

If you want to remove dead weight, yes. You'll have to find a non a/c drive belt.
