Where can I find a wiring diagram for the coolant temp circuit.

What is your question?

digital display shows dashes for coolant temp, then the ac. does not work. notice the cooling fans run constantly. now getting code p0128. unplugged the coolant temp sensor and module pins & sockets looked ok. checked the harness did not see any bare wires. code went inactive displayed showed coolant ac worked. this is a internment problem. I would like to overlay a harness for coolant temp rather than cut the harness open. any help would be appreciated
