WIRING PAGE
Current wiring notes (note, connector names from bentley manual):
- T2f (black connector by master cyl) R/Y should be fed to VEMS FP output
- PIN 15 on EC36
- T2f (black connector by master cyl) R/W should be fed to O2 sensor heater AND fuel injector power supply
- pin 3 on LS4U is heater supply
- Is running injection supply off of this source also going to be too much?
- Who knows! add 10a inline fuse if this ends up being supply for o2 and injection
- T3d (white connector by master cyl) black should feed VEMS +12v
- Pin 25 on EC36
Note: coolant bottle is removed for viewing.
Close up
- The top connector is a 2 pin mystery connector.
- Green and violet/black on the engine harness side (left).
- Green and blue on the main harness side (right).
- Green was for #50 starter trigger. Digifant needed it, VEMS doesn't.
- The middle connector is T3d per the Bentley manual in the 16v engine section.
- black on engine harness side and engine harness side
- Switched +12v
- Two wires from one pin, one wire from another pin on engine side (left)
- One loopback on main harness side (right) to power additional pin
- Red/black on engine harness side and main harness side
- I THINK this one gets +12v switched from lug on starter
- black on engine harness side and engine harness side
- The bottom 2 pin connector is T2f (the black connector)
- Red/yellow on both sidse
- From fuel pump relay output - route to ECU to allow priming.
- Red/White
- +12v switched that originally powered O2...will be used for that again.
- Red/yellow on both sidse
