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?
