The previous owner hacked the coolant temperature sensor connector/wiring on my 98 Talon TSi Awd. I noticed it when I got a code P0170 fuel trim bank 1. I found the hacked connector with one wire ripped out and electrical tape all over it. I connected the wires back together real quick to see if that would fix the P0170 and then it would only run for a second when started then die. So today I bought a ECT sensor from NAPA. I removed the two pins from the fubar connector and soldered them onto the existing wires. Once I installed the new ECT sesnor I connected the pins to it. I connected the female pins on the harness side to the pins in the sensor correctly and verified via telescoping mirror. The car runs again. I run a bluetooth OBD2 adapter and Torque Pro on my phone when I drive and when I'm home I have Evoscan v2.9 that I use with a 409.1 VAG COM. Evoscan said the coolant temperature scaling was 21-24*F and the Torque said the coolant temp was 120*F after running for 15 to 20 mins. The radiator fans wouldn't kick on and the coolant temperature gauge in the cluster would read a little hot. To keep the car cool I turned the A/C on which would run both fans at low speed. Then I took another look at the ECT sensor wires that I soldered on and found another wire (3rd wire) deep inside the plastic sleeve/loom. So there are three black wires, one or two have a white stripe.
I can get more pictures if needed.

And this is the Sensor I ordered.

I can grab pics of the wiring and old sensor if need be.. In my search I came up with threads discussing CTS and CAS being confused with ECT and couldn't find anything more explanatory to point me in the direction of finding out what's been done and what I need to do to correct this. Thanks in advance.
