2G multiple annoying electrical problems

[buhay6]

I'm having a few electrical gremlins that are starting to piss me off. First off is my windows won't go up or down but there getting power but I haven't yet checked how much currents getting between the switch and motor.
Next issue I'm not getting power to my heater motor switch, checked the drivers side fuse panel fuse was good but no power there either.
Radio isn't getting power either. I'm curious to know if there all connected some how?
My wipers are all wonky to but I know for sure that its a grounding problem.
I have two more quicker questions to ask as well (with pictures!)
1st what in the hell is this thing? What does it do? Connector # if possible so I have something to go off of. ( under dash drivers side tucked up above the fuse panels.)

2nd does anyone know what this connector is for? Connector #? Its been two years so I've kind of forgotten what was there. If completely ripped apart my interior again to try and figure this crap out. ( location center console radio area)

I don't have a 1g but ASA lists those part numbers in the first picture as "control unit, speed" so I assume it's the auto cruise control unit (connector C-01) if it has a 26 pin connector.

For the second one, check and read about C-67 here: http://www.dsmtuners.com/forums/articles-electrical-wiring/412841-1990-engine-control-wiring-harness.html.

For the windows. If you get power on the harness going to the door that's good. I'd apply 12 volts directly to the motor connector to see if the motor is good. If so then you may need to replace the button console.

Awesome guys exactly what I wanted to know. C-67 is the same through out 90 and ghe 91-94 chassis? (Nvm just read it now and answered my own qusstion)

I'm sure the motors good but at the same time I got this shell as a torn apart roller. I could always test resistance through it to I guess, believe there can't be more then a .2 drop in voltage correct me if I'm wrong..

No.

**C-67: Control Wiring Harness and Body Wiring Harness Combination (under center console)

When swapping this harness into a 1991-1994 1G, this connector will not match up. The 1990 car uses an 8-pin, 7-wire connector. Later manual transmission 1G cars have a 14-pin connector (see manual connector pin-out and a visual) where the later automatic 1Gs have an 18-pin connector (see auto connector pin-out).

Also see these for a visual on where this connector is accessed inside the vehicle:

The second picture shows a '91+ manual connector that was transferred into a 1990 vehicle which was undergoing a turbo conversion with a '91 engine, harness, and ECU. Note that this connector is shown with the foam shroud around it. For this particular connector pair, this is representative of the connector on the dash harness side, not the engine harness side. The third picture is the 1991 connector on the engine harness (i.e., no foam shroud).

The below is the pin-out for the various 1990 model variations.

1 -
M/T - NONE
A/T ONLY - YW, yellow with white, Power/Economy Change Over Switch pin 1 to TCU pin 9
2 -
M/T - RB, red with black, magnetic clutch relay pin 2 to ECU pin 65
A/T - Br, Brown, Accelerator Pedal Switch pin 1 to TCU pin 8
3 -
M/T - RB, red with black, fuse 19 to ECU pin 103 for battery back-up
A/T - RB & RW, red with black (male side) and red with white (female side)

• w/ Cruise Control - Auto Cruise Control Unit pin 13 to TCU pin 2
• w/o Cruise Control – Over Drive Switch pin 4 to TCU pin 2

4 -
M/T - 2.0L Turbo ONLY - BR, black with red, Boost Gauge (gauge cluster pin 6) to ECU pin 3
A/T - 2.0L – RG, red with green, Check Engine Light to ECU pin 64
5 -
M/T - LR, blue with red, fuse 3 to Power Window Relay pin 4
A/T - RB, red with black, Magnetic Clutch Relay pin 2 to ECU pin 65
6 -
M/T - Y, yellow, Self Diagnosis Check Connector pin 1 to ECU pin 1
A/T - RB, red with black, Fuse 19 to TCU pin 56 to ECU pin 103
7 - M/T ONLY - W, white, Self Diagnosis Check Connector pin 10 to ECU pin 2
8 -
M/T - RG, red with green, check engine light to ECU pin 64
A/T - YR, yellow with red, Self Diagnosis Check Connector pin 6 to TCU pin 19

The below are A/T only. The M/T connector has only the 8 pin slots.
9 - NONE
10 - LB, blue with black, fuse 7 to Inhibitor Switch pin 4 and TCU pin 11 and, LR, blue with red, to Auto Cruise Control Unit pin 6 on equipped vehicles
11 - NONE
12 - LR, blue with red, fuse 3 to Power Window Relay pin 4
13 - Y, yellow, Self Diagnosis Check Connector pin 1 to ECU pin 1
14 - W & YG, white on check connector side, yellow with green on connector side, changes back to white at ECU; Self Diagnosis Check Connector pin 10 to ECU pin 2

Just an update found that my C-67 connector was cut off at some point during its life so I wired in a spare one I had. Got power to both driver and passenger side windows! but no power still to radio or heater
definitely like to know what this connector all effects, if I can put it in the done pile of things or start doing more probing.

Little off topic but does anyone know of any threads detailing on power window's jumping out of track while closing?
