open up the ECU, write down all the pin markings. post here and I'll tag them for what they are, The wiring is simple. btw if your engine is distributor type you have a 4 pole crank sensor but no cam phase or TDC sensor. For a reference.
The engine markings you may find
10 - injector batch 1 (ground control) - injectors are fed with 12V positive from the key or main relay.
20 - injector batch 2 (ground control)
NE+ - crank sensor
NE- crank sensor
IGT- Ignitor trigger
IGF - Ignitor feedback
STA - starter 12V+ signal
E1 - main ground lines
OX - oxy sensor input
HT - oxy sensor heater circuit control to ground (if equipped)
RSO - rotary solenoid open
RSC - rotary solenoid close (idle control motor, it has 12V+ from main relay or key wiring to the centre pin)
PIM - MAP sensor signal
THA - air temperature sensor signal
THW - water temperature sensor signal
VTA - Throttle position sensor signal
IDL - idle switch signal in Throttle position sensor
W - check engine light ground signal
VC - 5V ref for TPS and MAP sensors and heated OXY sensor (if equipped)
E01 - sensor ground
SPD - vehicle speed
BATT - live
B+ switch ON
AC1 - A/C on signal
FC - fuel pump control circuit
cant remember more right now, too many phones going off on my desk, grrrrr
