The plan is to swap the motor out of my 1990 Turbo with the gray plug harness into a 1988 Turbo car with the yellow plug harness. What would be the easiest way of doing this? Can I use the yellow plug harness on my 90 motor or do I have to rewire the entire car for the gray plug harness?
Help with swapping in a 89+ Motor with grey plug harness into a 88

Use the yellow plug harness on the motor. ALWAYS use the harness that matches the CHASSIS of the car! That being said, you have a few options for the very few connectors that won't match up because of the newer motor w/ older harness.
1) just swap the sensors. That's the easiest way
2) De-pin the harness connectors and swap the connectors to the yellow harness.

Yep.
thats what i thought. what about....an 89ish ecu AND engine harness on a yellow plug and harness car? im trying to find options here. lol
What ever engine harness originally came with the car you need that harness and ecu unless you want to rewire the entire car.
For example I parted out my 90 turbo and took out the 90 motor/gray harness/gray ecu. I ended up buying a 88 turbo shell and I used my 7mgte from my 1990 but had to get a yellow plug 7mgte harness and ecu so it plugged into the car and I didn't have to spend a shit load of time trying to figure out where every wire goes and rig up the entire car, not worth it imo

A engine harness and ecu for an 87/88 is cheap, look around. The gray plug stuff is worth more you can sell the 89+ stuff and just buy the correct 88 yellow plug stuff and have left over money

I believe the camshaft position sensor's clips are different. Be careful when swapping the clips!
