Where Do The Ecu Earth Wires Ground?

trashy · Apr 9, 2011

Does anyone know where the earth wires on an ECU in a 1991 Eunos ground - the ones that are wired to 2A/2B/2C/2D on the ECU connector?

Is this two of them grounding on the engine block? If so, where does the other ground?

Cheers,

Paul

Go on, give me a clue, I've looked all over the engine bay...

I'm pretty sure they go into the block below the washer bottle; I've certainly always earthed my wideband O2 there for that reason.

the photo you show definately has something to do with the ecu earths.
If i remove this my megasquirt throws data connection errors... so i guess its pretty vital
