Under the dash connections?
 

Hi everyone,
I tackled the task of replacing the heater core and A/C condenser and everything is going well except their are a few plugs that I can't find the other connection to. If anyone can identify them in the picture what they go to I'd really appreciate it. As of right now everything seems to work on the car, but I don't want to put everything back on and then have to take everything back off.

This is right under the steering wheel.

This is near the left side kick panel.

Thanks for your help ahead of time. I can't wait to put it back together and drive my baby!

Does anyone recognize these plugs or know of a diagram on line?

bottom pic may be a dash speaker connection??

Yeah bottom picture looks like a dash speaker. Does it have an orange and blue wire? If so then its the dash speaker. The other is not used. I dont know what it is for but my car had that plug in it also. Only thing I can think of it possibly the horn contact plate on a non airbag car. Seems like Ford used the same harness for awhile. If you look at your fuse box if you have a hatchback car (and possibly a coupe also) youll see a fuse for a convertible top along with wiring for it in the dash harness.

Ok, Thanks guys. This makes me feel better.
You both say the bottom picture is the dash speaker, so I'm going to assume the right side dash speaker since the wire is on that side. The previous owner put in aftermarket speakers and it has aftermarket wiring to, so I'll check all of it today.
Thanks so much!

makes sense, thanks for the input.
