my recently purchased '93 EX coupe has doors from another Civic model (car was stolen before, stripped; next owner assembled it from peaces he was able to get).
I already fixed ECU problem (wrong ECU for my 16Z6).

Now I have sound problem.
Doors are from "manual" model (no power locks, windows, or mirrors). As a result input harness connector does not mach the plug (or whatewer it's called) hanging from the cockpit.
Don't care much about power-things. But I'd like to connect speakers somehow.
Dealer sells entire wire harness only (around $50 per door).
Tried junk-yard, they sell only as a set for manual-to-power conversion.
Where could I find connectors only? or, at least the name of the connector (Molex part number, for instance).
I tried to find any labels on the plug. Nothing, except "P*1"
