water thermosensor wiring HELP!!
 

my car is an88 turboII, with an rtek2.1 ... on the DIAGNOSTICS page, i have an error with my "water temp sensor"... so my coolant temp is always stuck at 176 degrees... i opened up the passenger floor to get to the ECU and i found that the pin is "2I" and sure enough, that wire was cut before it went out to the engine to the firewall... (really shitty harness from previous owner).. now my question is, i have to connect that wire to the water thermosensor behind the water pump housing, but that sensor has a 2 pin plug to it (like an injector clip) HOW DO I GO ABOUT CONNECTING THESE 2 wires when only 1 is going to the ECU??
