93 S500 cemtral lock pump UPDATE

[Goatman]

I finally received a new in the Bosch Box Cental Lock pump from an Ebay merchant. The price was $410 new original in sealed box (made in France)("merde") The old one had a burned out pump motor. (Looks like a cheap toy motor to me) Anyway, it took 5 minuters to install. To my surprise the central lock, the little "middle" fingers on the rear fenders and all other acessories started get alive again.

Thanks for all your help identifying the pump as a problem..

Does anybody know the meaning of the letters moldet next to the ports of the pump housing?

Must be German.
ZVR = Zentralverriegelung (Central Lock)

P+ ?
P- ?

there are 6 ports, I listed only 3. Would be nice to know what they control.

Thanks a lot RSMCMAHON! [:)]

This explains why there was no line connected to FKS on my 93 S500. The rear head restraint has a e-motor on my car.
