Wiring ?

Wiring ?
I removed the ECM from my 81 and trying to identify the wires that run under the console. I've looked through the TSM and schematics on different sites but the colors do not seem to match. I'd like to do away with the unnecessary wires that were attached to the ECM. Can you help identify these?
Thx
This is attached to the neutral safety switch
Where do these go?

AC switch?
Neutral safety switch?

Photo #4 looks like the communication link that was under you ash tray to access the ECM.
You photos are good but I need to see the ends of the connectors where wire terminals can bee seen. Much like you did in the first photo. So I need to see the color of the wires and the terminal ends.
The last photo..I have no clue on what you are asking about there. Normally when a photo is being taken..the subject matter is in the center of that photo and there is nothing there to see.

I've had a look at my 81, shop manual and wiring diagram so I'll take a stab (though I'm no where near the authority that DUB is)
^^^ I'm really not sure about this one. Possibly for the torque convertor lock-up. Maybe to the brake switch?
^^^ I believe this connects to the starter interrupt relay (part of the theft deterrent system). The relay should be on the aft right side of the console panel bracket (just in front of the shift lever).
^^^Pretty confident that this is the connector for the rear defroster. Top left-hand corner of the center console. The plastic pin fits into a recess in the bottom of the switch.
^^^ Diagnostic Check Connector. Wire colours should be; light blue, brown (white stripe), black (pink stripe), white (black stripe), black (white stripe).

Photo #1 is what appears to be the connector that attaches to the neutral safety switch IF the car is an automatic. IF it is a manual transmission car it is not used due to the clutch safety switch is used instead so this wire would not matter.
AS for the rest of these connectors...'StDomingos' is SPOT ON CORRECT

The bigger connector looks like the OBD connector -- was it directly under the ash tray? -- the way you access it is to remove the ash tray. If so -- it can be removed. I have no idea about the single wire connector, The only other sensor inside the car would be the Speed Sensor -- and that aint it!
BUT another thought -- the wiring harness that goes to the ECM is JUST for the ECM -- you can remove the whole thing.
