Grounds

[Speed Box]

What are all the grounds on a 89 civic/crx ?

1 on engine
2 on trans by the battery

I searched and everybody just mentions all the grounds are good etc.

My problem is I just swapped new motor car won't start and main relay buzzing. I ordered new relay.

AND there is a wire on the harness thats under the intake mani that looks like an O with wire , its coming from the harness itself I have no clue where it goes. it looks like it fits on the BACK of the starter (front is the battery wire) it could be a ground wire except where does it go?

that is the ground for the ECU and most of the sensors - it attaches to the thermostat housing with a bolt

Yeah thanks for your help!

There is a small bracket that "fat wire" harness hooks up to. I used that bolt just removed the bracket. It was 10mm and fit perfectly.
