As title says, need help with stock 4BT wiring harness. I have a Pre-91 KSB style with sensor in water jacket. I have two connectors I need help with. In picture attached I believe the #2 connector goes to the 12v keyed on connection. What does #1 get plugged too? Any help would be appreciated!

Blackduck596 thanks, that actually makes sense and would explain why in all my searching I have not found any related help. Wire #2 connects to the fuel selenoid. I have attached another picture showing.

Char1355 - I do have the sensor for the wax motor in the side of head. Is wire #2 original? Do both wires #1 and #2 get connected?
