ECU wires and pin connections:
In a previous message, someone had posted about how it might be
possible to measure the ohmage of the fuel injectors from the ECU harness
instead of the FI connector itself, with the added benefit of testing the
wiring harness leading to each FI as well. Nominal resistance is 10-14
ohms per FI.
You need to test the ohmage between pin/wire #58 (common positive) and
the following pins for each injector:
FI #1 - 101
FI #2 - 110
FI #3 - 103
FI #4 - 112
FI #5 - 105
FI #6 - 114
Other interesting pins of note:
#23 - Detonation sensor
#26 & #27 - AirFlow Meter
#25 - Wastegate valve control
#18 - Fuel Pump Relay
Some things NOT to try to meter:
#115 & #29 - Right Oxy Sensor
#115 & #55 - Left Oxy Sensor
Voltage sent through the O2 sensors will ruin them, use the ECU self
diagnostic instead.
