It would seem like the issue is related to having too many options. If you just pick one option and wire it exactly like that, it should work. I assumed the T.C ecu would ground the merkur relay out to close fan circuit at the preset T.C ecu temp but it must need more input to keep it open till the close circuit temp is reached .. I guess simple is best and I'll go with the 84 mustang fan circuit with ign power, relay and 227 degree grounding switch as I originally planned, then stick in a lower temp ground to close the activation circuit at a lower temp...say 200-210 degrees....THANX!
