[Request] Mitsubishi Montero/Shogun Gearbox Wiring Diagram

Evening all,
Got here a 2001 Montero 3.2 with center differential lock light flashing as soon as you move the 4x4 select lever with just ignition on, i've checked vacuum pipes, solenoids, front differential lock and switch, all good.
Need if possible a few pages from, if anyone has, from Nissan Service Manual with 4x4 description, operation, fault finding and wiring if possible.

VIN: JMBLNV78W1J000164

Thanks.
