Z31T ECU Swap Questions
#151
#16 is typo. I know that air regulator is not needed to start the engine, but I connected a resistor to ecu to reflect the air regulator just to make sure that the air regulator isn't the problem. Ohm value I checked from the FSM.
#3 is connected to ecu and the power transistor like it is shown in the wiring diagram.
Power transistor wire colors change with facelift-models and if you buy a new power transistor, you'll get the one with new wire colors. But I have to check wires, how they go.
I read your excel file and I have used from the beginning. Next thing, which I'm going to do is that I will check wiring harness and make sure it is the same as in US models.
And sorry about my english. It used to be better, but now it's what it is...

Well, I checked the wiring harness and it's almost the same. Expect #24 is empty and #115 goes to one of those connectors, which you can see in the pictures. I tried to find out where these connectors originally go, but I couldn't find out. Any idea? The connectors are close to the rubber, which seal the hole in the firewall.
I read the z31 na ecu swap topic and there was something said about ignition module. What is called in the FSM?

One really big problem I noticed even with my Z31 is that it seems like the Z31 harness was built with every model of Z31 in mind. My 87' Turbo has a bunch of spare plugs in the engine bay that don't seem to go anywhere. Like they were put there for other features of the different models. Or different sensors for N/A models, etc.

Looks like the whole problem is the harness. It's from euro z31 without exhaust gas sensor and therefore the wiring diagrams which I have looked doesn't apply. But now I'm modifying the harness to mach the 84 US harness.
