    Ok got it. Connector C1 thats the top one on the PCM. Terminal 26 its an orange wire with a black tracer. I think its the only one in that connector anyway. Also you will need to unplug the connector on the sensor and fill both ends with dielectric grease.. dont let them corrode. BTW the fans will run continiously. Hope this helps.
