Marlin,
There is only one (green) wire going to the 2-spaded connector for this temperature SWITCH (in retrospect, I do not think it is a sender, but rather a switch). My understanding is that there is a jumper wire between the two female connections of the harness and that once the temp gets to a prescribed level the connection is completed and sends a signal to the TCS switch.
