I had a lot of problems with my locking a while ago, and nobody being able to helpme, I went on a voyage of exploration.
First, I have a Masterace Surf 2 wd auto 1990, and having read all the descriptions of control boxes under the steering column, and not finding one I became quite worried.
The US Van site has a handbook, which is not much use for the Japanese vans as a rule, but the wiring diagram shows the locking system clearly, and using this, I found it almost exactly equated to mine- with differences in wiring colours.
The circuit is fed from one of the fuse links down the trap-door behind the driver's seat, and thence to the circuit breaker on the relay panel under the dash. This then feeds direct to the switch on the arm rest but without any relay box in between. The US Van diagram shows the sun roofs on the same circuit, but of course we do not have these on our versions.
My original problem- a total failure of the locking system was due to the fuse behind the driver's seat blowing. Easily replaced, and system working well.
