Thanks Paddles, now a while since we met.
I was hoping you would chime in here. This network has everything, even a Kiwi fluent in Japanese.
I have some text in Japanese writing describing the system, which I believe was copied off a web site 6/7 years back. It includes several illustrations and you may know of it. It would appear to constitute an advertising screed so may not include much technical data.
A local guy who I have lost touch with, sorted out trouble he had with the electronics in his own 4WS SVX and I have some info. You are correct in that all indicates a Mitsibishi system. The actuating electric motor is a Mitsibishi Electric Type 4WS - 88141PA000. The controller mounted in the boot/trunk, is a Mitsibishi Electric Type 4WS - 88121PA00 and switches the motor via a 45 amp rated FET which is stall current protected. N.B. The controller is permanently activated and therefore a fault could result in a flat battery.
Cheers, Trevor.
