Electrical harness for power features compatibility 90-93 240sx hatchback?

[jerryk]

I have a 1990 240sx 5 speed SE hatch with complete power A/C P/S P/B P/windows P/locks p/antenna P/mirrors rear wiper and cruse control. I love my car but the front underbody is in poor shape with severe rust. The rest of the car is in wonderful shape. I am looking for a replacement 90-93 model with better frame condition. If I find a 240SX within these years that does not have all these features will the harness be the same so I can swap in all my parts without rewiring? Example: car with no rear wiper or power windows etc.

Also I purchased LSD and counterforce clutch for my 1990 will these parts fit in the 91-93 240SX hatchbacks?

If the car didnt have the options most likely it wont have the wiring to support those options. I have seen this in a Ford Taurus and in my 240sx swap 91, DOHC engine into 89 SOHC body.

In junkyards I have seen a 91 240 with manual transmission and no cruise was missing 4 pins and wires in the brown connector in the dash that goes to the instrument cluster. And for my 89 body the instrument cluster didnt have the pins in the right spot so i took that 91 connector from the junkyard and carefully removed the pins from the 89 dash harness and put them in the 91 dash harness connector in the proper locations to avoid cutting and soldering.

There are still some connectors I have yet to re-arange, but its primarily for my auto transmission control unit which seems to shift just fine without reading the engine ECU. The auto will be yanked sometime soon for a 5-speed swap soon hopefully. And the Cruise control which worked fine in both cars didnt work after the swap until I jumpered the speed sensor wire from the dash harness to the cruise control module.
