quick question,

Is there an OBD1 to OBD2a Jumper harness so I can use a OBD2a GSR ECU in the civic? Or do I need to get an OBD1 GSR ECU?

 

you'll wanna get an obd1 ecu its easier than wiring up other sensors to get it to run right and its better for tuning in the future.

 

duh, forgot about the rear O2 sensor. Ok scratch that idea.

Anyone have a link that shows me which wires need to be pinned on the ecu plugs and shock tower plugs? (VTEC oil pressue, VTEC Solenoid, Knock Sensor, IAB)

 

I have done this swap. It all plug n play. Use the obd2 engine harness, which plugs up to the stock eg harness, and just run a chipped p28 that will let you disable knock and o2. Easy as pie!

or go to locash racing and get a obd1-obd2a jumper. i used it on my gsr and it worked great to me.
