Started wiring.
1993 5SFE with ECU 89661-17430
discovered I did not have the ECU body plug - 12-pin connector
Luckily I had a harness in my large collection of harnesses that had this guy.
Using Paul Woods 3SGTE MK1 Wiring Guide v1.0 PDF

E6 B 12-Pin Grey Connector on ECU
1. +B1 = EFI Main Relay
2. Batt = Battery
3. ACA = A/C Compressor
4. FC = Circuit Opening Relay
5. Empty
6. ACT = A/C Compressor
7. +B = EFI Main Relay
8. W = CEL Check Engine Light
9. Empty
10. ATS = A/C Compressor
11. SPD = Vehicle Speed Sensor
12. ELS = Headlight and defogger relay
I am not using A/C - so ACA, ACT and ATS wont be used.
I have the circuit opening relay wired and the starting circuit wired.
Circuit Opening Relay
1. Fuel Pump to Pin 18 on AW11 N1
2. To ECU Pin 1 (+B) and Pin 7 (+B1) on on 12-pin gray ECU Connector, and Pin 7 on AW11 N1
3. To Starter 4-Pin Black/White and STA Pin 2 on 26-Pin ECU Connector Gray
4. To Pin 4 (FC) on ECU 12-pin connector
5. To Chassis Ground (White)
The starter solenoid is wired as well per Paul Woods diagrams
That is where I stand now.
Tomorrow night I will work on the Charging Circuit.
