Harness Identification

[CO MJ]

My PO did a very poor job swapping an auto trans into my 89 comanche. As far as I can tell, the engine control harness is the factory manual one, but for some reason the wires for the CPS go through their own grommet in the firewall next to the big one for the ECU. Anyone ever seen that before? the two CPS wires in the engine control harness are cut, and the original CPS connector is still there. Weird.

Anywho, I have this other harness with all the TCU wiring that I pulled from the yard, but for whatever reason I did not take note of the year. It looks identical except for connectors c103 and c109 on the left hand side of the diagram. Shown in the photo are the connectors on the new harness. My plan is to trace these wires, and replace the connectors with the c103 and c109 connectors from my original harness (planning on tracing every wire on the ecu/tcu connectors as well to verify they are correct, but all the wire colors match so I'm hopeful).

Colors on the c113 seem to be the same as my original harness, but in a slightly different arrangement. Between the c103 and c109 on the old harness there are 11 wires, but the new one has 13. Any features in newer years that might account for the extra pair?

If anyone happens to know what year this new harness might be out of based on these connectors that would be super helpful!
