I'm trying to power up an ECU from a H25 engined GV. I don't have the EFI schematic so I'm trying to work from the wiring diagram. If I understand it correctly then the ECU connectors are the mirror image of the connectors shown in the diagram and the connectors are not ordered left to right (or right to left).
If anyone has a H25 engined GV can they please tell me which pins have the black/blue and the blue/black wires - and whoever came up with that scheme should be shot!

The wallpaper sucks but it was there whan I moved in :oops:

I agree with you there! Makes it nice and easy to mix up the wiring. Think the also used black in some applications as V+ as well! What ever happened to a bit of simple common sense?

Nice wall paper btw :wink:

Is this any help? I probably have 2~3 more if it doesn't match what you're looking at.

I'll check that schematic tonight, thats the type of diagram I was looking for. I have an electronic copy of the FSM but all the EFI stuff (volume 2) seems to be missing.

Whoops - that should have been included in the first pdf - sorry about that.
