I was wondering, cause the damn thing came on on me the other day. I hooked up the battery, to find suitable power/ign/light wires for my gauges, and the damn thing was on. I unplugged it, and a light came on in the idiot cluster. Just wondering what turns it on.

The car had no coolant in it and hasnt been run yet.

 

i have been meaning to start a thread about it! im wondering as well..

 

There is a sensor up by the filler neck, if you unplug it the fan will stay on all the time.

 

green wire? i have the wire/plug, but nothing to connect it to...

funny you mention that, today i was looking at an automatic 86 GXL, and it had that wire plugged into something on the filler neck that my filler neck does NOT have..

 

The A/C turns it on. Also, if your temp gets to something like 208º

 

Im wiring mine to come on with my main efan. Cant hurt, right?

 

theres an idea.. lol..

how you gonna make it not tamper with the gauge light?

 

I wonder if my A/C compressor not being is has something to do with it. Maybe the wire is grounding somewhere.
