I ended up having to use the 4 wire sensor and run 2 new wires. One is a ground, and the other has to go to the black XR2 connector in the trunk. I ran the ground to the trunk as well and tapped into the original ground source just to be safe.

Aaron,
I’m working through this exact same issue on my car that I replaced the engine on. Could you provide some more detail on how you connected onto the 4 pin temp sensor, got the two “original” wires to the 2 pin connector on the engine harness, and where/how the two “added” wires connect into the XR2 connector?
I’m competent enough with nuts and bolts to do the engine swap but electrical stuff is outside of my knowledge base. Thanks!
