I just check mine, the bullet connector sub harness is marked with some red tap wrapped near the bullets. that is the THERMOTIME harness, the other sub harness wth NO RED TAPE is the CTS. You can just disconnect there leave the sensor plug attached to the sensor, and get a reading off the bullets (the side that is plugged in) you should see somewhere around 2k-1.2k (2000 to 1200) ohms, depending on local temps (cold motor). Once it has warmed up you should see around .3k or 300 ohms. that would be around 180f water temps. Trace the wire harness from the CTS and follow it back toward the firewall along the top of the engine. You should be able to find the bullet connectors. Make sure you don't break the wires when you disconnect it, they will prob be stuck. again you should see a RED piece of tape wrapped around the harness near the bullets, that is the harness for the thermotime, it matches the main harness also marked with red tape. You want the NON red tape for the CTS wires.
