A man has got to know his limitations.....
So at this point you know for sure it's not grounding through the SMEC. As others have said, clean up the grounds. I'm still at a loss with this whole deal though.
Do you have all your grounds hooked up? Injector rail, cylinder head, trans. Also make sure the ground straps are installed that connect the engine to the body, and make sure the battery negative terminal is grounded to the body also, not just to the engine.
Back probing with it plugged in, looked @ the pin in the connector, it looks better than all the others around it. Does that connector come apart or the pins just latch down in it?

Maybe i am a bit late to this thread to be saying this now but why has noone ever questioned the CTS circuit itself? All it has to do is show some kind of resistance number that is within the huge resistance range of a CTS, and the computer would think it was always hooked up whether it was plugged in or not.
It would be very easy to diagnose this with any kind of scan tool whatsoever. Which, from buying both, i'll tell you that a used scanner that will work on these cars is basically the same price as a spare computer anyway.
If you know how to back 60-way terminals out i would back out one of the CTS circuit wires to cause an open circuit AT the computer and see if it then turns on the fan. That rules out the possibility of the CTS circuit having some sort of high-resistance short that would simulate the CTS being hooked up.

Well if the fans not kicking on with it unplugged (infinite resistance) it wouldnt kick on just from heating up the sensor either because all that does is raise its resistance.

Yeah that's the kicker, why isn't it coming on when it's pulled. :-\
Joe, the red piece will come out of the plug and then there is a release for the pin. Aside from unwrapping the wires from the CTS area to the plug, I just can't imagine what is causing the issue. If you guys didn't unwrap that area from the lower harness up to the plug, that would be my next suggestion. I know the CTS wires are tied into the harness in a couple of places and since we checked the wires to the SMEC, that would be the last thing to check, in my opinion. It has to be something simple we're overlooking.
Vigo, you coming to SDAC? Franzen is coming, btw.

I want to, but i'm going to Canada the next weekend so i'm iffy on over committing myself in time and money. I dont think SDAC is ever going to get any closer to me than this, though!

I'll see if i can rope someone into keeping me company for the trip.

by any chance is it csx-t 315?
Made good progress this evening, got the radiator mounted and the fan works as it should now. The problem was that the speed sensor was unplugged for some crazy reason.

Never heard that one before! I'm pretty sure i've had numerous non-working speed sensors in my vehicles and im pretty sure SOME of them were unplugged and i never had this problem. But thanks for the update!
