I'm replacing the oxygen sensor in my 85 with a silvertop engine. I bought a generic 4 wire sensor and I'm not sure how to hook it up. The sensor has 2 white, 1 black, and 1 tan wire.
Here's what I've found about 3 of the 4 wires on the car:
Black screened wire - Input from sensor
Red w/ Black stripe - Input from sensor
Pink w/ Black stripe - Sensor heater
Black w/ Red stripe - ?

The oxygen sensor wasn't hooked up so I'm pretty sure these are the right wires since these four wires are together in the loom and are the correct length.

Any ideas on the correct connection?
