Where do these connectors plug in?

[Amphiron]

Where do these go and is this why my coolant gauge isn't working? They stem off of the same harness the alternator goes to and shoots down by the radiator but I can't find anything to plug them into.

Are they down low? They look like the secondary O2 sensor plugs.

EDIT: yea the pic looks like it was taken by the subframe. I'm sticking with my answer.

Downstream O2 sensor connectors.

Hmm I'm starting to wonder if these were ever plugged in at all because theres nothing around them to plug into. Maybe thats why I was getting a CEL before the rebuild.

The plugs would plug into the secondary o2 sensors... and if they aren't there, then you wouldn't see anything to plug them into.

Do you have an aftermarket DP with no secondary o2 bungs by any chance?

You probably just have a Fed-spec and not a Cali-spec. Read the sticker on the hood that says "This vehicle conforms to...". If you don't see "California regulations" somewhere in that paragraph, you've found your answer.

If they are coming off of your harness for the alternator, then they are the upstream front O2 sensor and the AC compressor. The down stream O2 sensors that the other people are talking about come off of the engine harness.

Damn, you're good.

Again, not sure if fed specs had secondary 02 sensors, but if they did, they'd be on the downpipe.

Should my downpipe have a o2 sensor coming off it? because on the exhaust theres only 1 o2 sensor and I think its behind or around the precat. Thanks everyone for the help, a lot more replies then I got on that other shithole =]

Are you running a jspec engine? If so, there will be only one O2 sensor, but it will be in the non-turbo location. If you have one in your downpipe, you should really have 2... then it would be a cali spec car. There should be 1 O2 sensor directly after each turbo (before the actual precat material) and another sensor after each precat (if you are cali spec) that are located in the downpipe.
