sounds like it. its a single post connector, second from the front, so about level with cylinder 2/3.

mine didn't have anything connected to it originally so I have no idea what its supposed to be used for but my mechanic ran a connector and cable from it back to the fuse box and spliced it into the sensor feed going into the high speed fan relay, thereby bringing the fan in early at 85deg. I think it actually cuts in just over 80 deg.

since my cooling system is now up to scratch and I know the high temp sensor is working, I disconnected it because I was worried about the engine not getting up to operating temp and out of warm up enrichment, which i think was more to do with a bad fuel distributor than irrational fears about the engine not warming up. have now changed the fd and stopped worrying about that.

anyway, because I was bored, I reconnected the cable and wired up a red push button switch into an available hole in my dash fascia so I can switch the fan to high speed if I ever feel the need in traffic.

bwaaahhaahaaaa
