1990 Civic Hatch 1.5L

Where is the "Ignition timing adjusting connector"? I am trying to adjust the timing and the book says I need to connect a jumper to this...

and ... Why?

 

try looking at the distributor, the wires that plug into it that go to the spark plugs

 

It's under your carpet where the ECU is. You'll see a 2 pin connector, you'll need to jump this. I didn't know this was also needed in pre-1992 models. Aren't those OBD-0? Nonetheless, you need to jump the service connector so the ECU won't try to place the timing where it was after you adjust it. At least it's this way for 1992+ so it might be the same with 1992 and older. Not sure but it sounds the same. Don't quote me. Plus, you're in the wrong forums. This is 1992+.

 

Thanks very much! The book was not specific and it also referred to the SAME location as 1992+, but NEVER told me where it was!! Darn Haynes Manual...

 

Bump, where is this connector in an EG hatch? By the ECU?

 

its a blue connector that should be to the right of the glove box above the ecu. and i usually bend a paper clip and use that to jump the connector.
