I'm chasing a possible bad earth in my EF, and also thought it would be helpful for others to have all of the ECU earth point locations documented on the site.

See attached "Fuel and engine management system" ECU wiring diagram from the Gregory's manual, with numbering added on each earth point.

Here are the ones I know, if anyone knows the others post them and I'll modify this post:

1: Battery Earth - Bolted to the chassis between the battery and the coolant overflow tank.
2: Black - Location ??? possibly somewhere near fuel pump?
3: Black - Location ??? possibly somewhere near ECU control relay which is under coolant overflow tank?
4: Black - Location ???
5: Black with Dark Green trace - Screwed into ECU retaining bracket in passenger kick panel.
6: Grey with White trace - Bolted to block under inlet manifold.

For now I'm focussing on the ECU Fuel and engine management circuit, but if anyone's interested in the other circuits (BCM, instrumentation, illumination etc.) we can expand it to include those as well later.

Cheers
