Subaru Conversion Information Resource Navigation Bar - over 160 pages of info on Subaru powered VW’s! :
ECU, Fuses, etc.
The ECU, relays, fuses, etc were initially left unattached and unwrapped to aid trouble shooting. This harness was modified with no diagram, as it's a wierd Japanese spec engine. Subaru ECU's are not waterproof - they must be installed inside the VW, not in the engine bay - especially in a Syncro!
