Need Permolock C3 button / wiring diagram

[xtal_01]

My wife has a van with a Permolock C3 ... discontinued years ago.

Does anyone have a wiring diagram and/or parts supplier for a Permolock C3 (Permobil floor lock).

Then you press the button it no longer opens the lock (should release in 3 - 5 seconds). If you hold it for 10 seconds, it opens on "reset" (you do this if the chair does not lock in correctly and gets stuck in the mount) ... so I know the motor works ... and the green light comes on with you lock in so I know the limit switches are working ... just won't release when you press the button (just fyi, the green light goes off after a few seconds when the van is shut off ... it use to say on till you released)

The push button part number is: Art. no. 1824735

I am sure the "standard" button will also work New - 311364 Old - 311364-00-0

I am hoping to either find a button or to find a wiring diagram so I can try repairing the one I have.

Any advice would be appreciated.

Thanks
