Re: ECU Ground Wire

Hi Scott.

Thanks for the clarification!
Actually i thought i should go GroundWire-hunting.

However, the ground wire from the rear valve cover to the firewall bracket
for the ignition coil.....
Doesn't quite seem to be present.. - Will be soon !

As I'm thinking of making a seperate ground wire from the battery to the
engine, maybe the IM, i wonder wether it will cause a ground loop in
parallel with the original ground wich will inflict on sensor accuracy etc ?

Thanks !

Kenn
