The following items are found on Classics up to the '91 my.

Under the dash are relays.

Headlamp relay
Heated front windshield relay
Ignition load relay
Starter solenoid relay
Heated rear window relay

Back row (left to right).

front to back:

Sunroof aux. relay
Aux lamp (fog or driving lights) relay.
Flasher/hazard unit

Under steering column/lower dash panel are the door lock control unit (Kierkirt brand), and the audible warning unit.
These are mounted to the cross member supporting the dash.

Up under the dash support is a low oil warning logic unit.

On the lower dash panel is warning lamp control unit.
Also found here is the dash light dimmer.

Thanks for the replies. I really appreciate it!

I'm pretty sure the door lock controler and dimmer controler are among the missing parts since neither of those two systems work when I put power on the car. The other systems that do not seem to function are the dash lights, winshield wipers, windshield washer pump, power mirrors, power windows (the sun roof works though), and heater controls. All of the exterior lights and the dome light work. The start motor clicks but the engine won't turn over, but this may be because I didn't have a high-amp electrical source hooked up to it.

Also when I put power on the car there is a pump/motor assy attached to the master cylinder that runs and does not shut off. Is there some kind of brake conroler under the dash too?

I am attaching a picture of the under-steering coulmn area showing the loose wire terminals. I can post more pictures if you like, but I don't want to waste a bunch of server space if I don't have to.

Thanks again for your help!
