Comparison of black Ford warning chime modules WCMs from 1992 to…

WIper Control Modules used from '92-up

I used to think they all took the same module, but the white connector is keyed differently from the gray. The years beside them are ONLY for the part number codes - not necessarily the application years.

The primary difference is that the WCM for a vehicle with hidden wipers has to reverse its motor to park, so it needs another relay. The '92 & '93 WCMs have only 3; the '95 has 4.
