Electrical connection

When I put the motor back in last weekend, I have one loose connector that I can't seem to figure out where it goes to and where the other half is. Can someone look at the picture and let me know. It is right by the Oxygen sensor.



Thanks,
Dustin

That looks extremely similar to the quick connect on my battery tender, I'm not by my car right now to say for sure if it's 100% like that or if there's another connection that uses that, just a thought though

Are you using the single wire O2 sensor (outside California)? If so, I think that connector is for the CA sensor, the wiring harness will contain both O2 connections. Disregard that one unless I'm totally wrong however; I have the same unused connector on my 84.

As above. thats the heated connector to connect a 3 wire O2 sensor, which where required when originally sold in California. The rest of the US used the non-heated 1 wire sensor. I'd assume many (all?) cars came with the 3 wires on the harness, whether the heated or non-heated sensor was used.

Ok, great. Must have been that way and I forgot when I disconnected everything.

Thanks
