It is listed in RAVE as ' with ship disable' or something like that....
Even from looking in the wiring manuals, I can't decipher what it ACTUALLY does, or how it would be useful.
The connector shows as "NOT USED" in RAVE - but one wire comes from a splice in the wire from BECM to the ignition relay, and the other a splice in the wire from the engine ECU to the main engine control relay.
My guess is there was either a bridge wire, or an external box that plugged into it to disable the relays from being energised or the vehicle started in transport?
But it is a standard, unused, connector on later Thor model P38's - and can just be left to it's own devices.
