Car is ae86 gts, so driving home last night then cel pops so I got home then jump it came out to be o2 sensor went to check where the wire broke off I've tried looking for that damn o2 wire this morning but no luck and I know for sure it's on the engine harness can anyone pinpoint me where/what's next to that damn wire man I might need to get my eyes check anyway thanks

best shot i could find. the yellow part is from the harness. usually the O2 side is yellow as well, but i have a bosch replacement and the plug is black.

If you stasrt at the O2 sensor, grab the fire, swing it toward the shock tower. There's only so much slack on that wire, you should see the pack connector dangling there somewhere.

On the '85 it is a single wire.

If a PO replaced your O2 sensor with a cheapo third-party one, they might have just twisted it and taped it, some folks want to save five bucks by doing it that way. The wire can be repaired but it your sensor is ~75,000 miles old? Replace it anyway, they slowly wear out and reduce you power and mileage.

I've also got a Bosch, offhand I think ~$40 including the right connector.

Thanks guys
