These next posts from me will be a recap of this project done over the past half year, for me I am a bit stunned since parts of this have consumed many more hours than anticipated. What project doesn't.

I am melding the original 2008 Eclipse PCM harness to the 3rd gen Montero transmission, and both of these are blended into the RHD '93 Pajero chassis / body. My original estimate to build the harness was in the 450 - 500 hr range. I am just over that now and feel I have about 100 more to go, which was my estimate 300 hrs ago.
As such the original Eclipse powertrain control unit will both run the engine and shift the transmission. The original cable throttle is now throttle by wire. I intend to add paddle shifters to the Pajero column so both the floor shifter and paddles can be utilized in Sport / Manual mode. I kind of desire to add cruise control too which is fully incorporated within the PCM but there is simply a space conflict on the steering column where the paddleshifters and cruise switch need share real estate. I will run the wires for each and figure this out later.

The transfer case is the electrically shifted Gen 3 unit so this utilizes a processor and wires. Not my favorite idea but all my SR T cases are mated to something be it the SR I currently drive or the custom 6 speed manual I built for a Montero, that may well be my next project which is an all independent suspended twin turbo driveline. I can post pics of some of this later. Not sure if that one will be under my old red 87 or an SR body. Original thinking was to shorten a Gen 2 down but no need for that since I now own the real thing. I almost wrote "The real Monti"
A few images, I apologize for the clutter in my shop but it is no different than what is inside my head since this is not my only project I am working on at this time.
This pic was shot back in mid Sept '20 and is part way through the disassembly of the transmission wiring prep before the engine had arrived.
