Blacktop SR + 93' Chassis - Wiring Questions

[omgdudewtf]

The blacktop and harness and ecu came from a RUNNING 89 automatic chassis. My 93 is also auto, if it matters.

I have a BUNCH of connectors near the fuse box and 1 near the ECU that are not matching up.

Like I said, the harness from the ECU and the lower harness (alternator, starter) came from an 89 auto (converted) chassis. I have not done anything with the wiring on my 93 to convert it to manual, I've just installed clutch hydraulic parts and the pedal.

Do I need another harness from a different year, motor or chassis? This is not making sense to me.

Cliffs:Blacktop SR, ECU, and harnesses from an 89' auto chassis (converted to manual) going into a 93' auto chassis (also converted). Plugs are not matching up near the fuse box.

Will the current harness work if it was in an 89 car?
