You seem to be pretty familiar with this issue. I have a 97 that had the thermal actuator. Got a motor actuator and wiring harness and tried to hook it up tonight. First problem, the two prong connector on the new harness that I assume is meant to connect to the existing wiring for the thermal actuator is slightly different than the connector on the frame and won't connect. Just to test, we try to connect the wires to see if it will work. No luck. The other problem we have is we don't know what the long brown wire is for. Supposed to go to "CKT 241 (BRN) BETWEEN CONNECTORS C120 AND C100". Without a wiring diagram, it's hard to know where this is.
Do you know what this wire is for?
Can you tell me where to connect it?
Thanks in advance. Appreciate your help to others that I've been reading.
