 |
|
I'm actually working on a sand rail. It sat outside uncovered for about 20 years, so the original engine got water inside and it started to fall apart. I picked up a 1980 Vanagon drivetrain (engine number CV043944), took a little fabricating to get it mounted. My issue now is the wiring. Every single wire on the ECU harness is white.... There are only 2 connectors to the vehicle, a 6-wire rectangular and one that looks almost like a relay connector. I have the relay that was attached to the starter.
All the wiring diagrams I see have color-coded wires, so I am at a loss how to get this up and running. I assume that at a minimum I need power and ground to the ECU and power from the ECU to the fuel pump. I will have other wiring questions later, but I'll settle for this now. |

This should help for part of what you're doing. Info on the "double relay" wiring, operation, and possible substitute of 2 generic relays for the VW part:

The Bay Window forum here should have more info on the fuel injected 2.0 as it was used in late model year Bays
If you don't have a Vanagon Bentley manual, a Haynes air cooled version should help and may have an ECU pin out test table that would help ID ECU pin numbers to their parts.
