I picked up a very nice '91 Carrera2 Targa. Of course, a couple of days in, I get the electrical gremlins . In this case, the little switch that tells the airbag controller that the driver-side seatbelt has been buckled seems to be faulty leaving me with a seatbelt unbuckled and an airbag light.
I am also looking for a way to disable the passenger airbag, possibly put a switch on the igniter so I can take one of my kids in the front seat.

Where would I be able to find a maintenance manual for the 964 with the wiring diagrams, procedures etc. ?
