Coolant sensor wiring

[Ryebonti123]

Hey guys. Im trying to wire a coolant temp sensor using the factory harness. 86 regal 307. I dropped in a 383. I have two green wires, one with a white strip and a brownish one outstanding all coming from the engine harness.... not sure if the factory sensor was a 2 wire?? Any body know?
