Temp Coolant Sensor Education 200 1984

I have a 1984 240 with B23F engine with Bosch distributer. When I changed my wiring harness I noticed the dealer had spliced into the old harness and grounded out the temp coolant sensor. When i changed the harness I did not make this change. i contacted the dealer and they checked my records. They said there was a bulletin and the change was made because during warm up the car may put out too much emissions. The service manager read me the bulliten and while it dealt with the coolant temp sensor it was much more involved than running the coolant temp sensor to ground( bulltin called for wiring changes on ECU plug.) The car starts fine cold, but after 20-30 secs it lopes a little. Grounding out the sensor disables it right? I am wondering if I should make the harness the same as the one that was removed.

What role does the temp coolant sensor have in the system?
