I found an 85 Turbo complete and the JY is cheap, so I was going to grab the entire system. I read through the sticky (Afshin) converting the 81-83 harness to use the Z31 ECU, but curious to those who used the Z31 harness, not the ZX.

Reading through the FSM I made two list; Must and Don't know. Can anyone tell me what you did to the Don't know list if you didn't end up using it? Did you just leave it unplugged? Jump it? Etc.

Must
ECU
CAS
MAF
Head Temp Sensor
Exhaust Gas Sensor (O2)
TPS
Dentonation Sensor (Knock sensor)
Coil

Don't Know
Vehicle Speed Sensor (Just Unhook?) Where is this even located?
Fuel Temp Sensor (Just Unhook?)
Power Transistor (Just splice around?)
Idle-up Solenoid valve (Just omit?)
EGR Control Solenoid valve (Just omit?)
Air Regulator (Just omit?)
Air Injection Valve (Just omit?)
AIV Control Solenoid valve (Just omit?)

I did find it interesting the FSM calls the MAF an AFM.
