S5 n/a vs S5 turbo 2 engine harness

Im finishing up my turbo 2 swap in my 90 gtu. I have an s5 na engine harness and have heard all the connectors are the same except the tps and something to do with the o2 sensor. Are these the only differences between the two harnesses.

Plug 6PI plug into turbo duty solenoid (Pin 3R) if you still have it in your car which i do not so this step can be skipped if all the emissions and "unecessary things" are removed

i used one a couple years ago, the TPS plugged right in, and then the only real difference is that the NA has two solenoid connectors and the turbo is a knock sensor and the boost solenoid.

the boost solenoid and emissions solenoid have the same two wires, so you just need to change the connector, or use the NA solenoid...

the knock sensor can just be hooked to the ground side of the NA connector, the only difference is that the T2 is shielded.

piece of cake!
