Got this hatch in trade, Ran like **** but was worth twice as much my trade.

Guy said it ran bad because the ecu, had a jumper harness blah blah blah.

Figured I could just throw in a obd2a dx ecu and it would be find, but it doesn't plug in


Runs with the jumper harness plugged in, but not without, tach / speedo dont work as well.


Pictures of said problem.

 

what year is ur hatch?

 

96 DX like says in title.

On the bottom picture, its the right grey plug that wont plug into any obd2a ecu's I have.

 

What harness is in it? Looks like a '99 - '00 Harness in a '96 - '98 civic to me.

 

I'm pretty sure its a obd2a, because it has all 4 plugs, the 3 into the ecu and the green plug.
