I have a 1995 S600 with a PSE (Central locking pump) number 1408002348

All of the new pumps have less nipples or outlets in them. Is there some sort of outline as to how to connect many more hoses to the fewer available ports?

Or would it be better to try to have mine rebuilt or find a working one? My pump part is fine, the dealer told me that the internal electronics have some problems. The trunk handle come out after a while. I think it would have to be blowing air back out to make that happen?

Every "Nipple" for it's door.

The pump is calibrated to a certain amount of pressure. If you have more suckers than the pressure required, it will just trigger the pump to shut down.

its a diffrent pump the old one 91-94 is made by hella and has a removable manifold on top 95-up is bosh and has extra hoses running around that make things stupidly complicated and fragile.

^ the manifold is removable... So is the pump motor... From what I've read here... Had to replace and found one that was exact but I did some experimentation on the old one... It's straight forward... Good luck.
