Trying to swap a GSR in an EK hatch, ? I have is what harness would you go with I have an 99 SI but not sure if it will work. SO what should I use SI, EX or what? Thnx

 

Use the 99 Si harness you have

 

BTW the hatch is an 97 if that means anything

 

I have a 97 hatch and just dropped in a 00 B16a2. This is how I did my swap after I called Jotech in Garland,Tx for help.

96-98 civic is a OBD2a setup. And the 99-00 B16a2 is a OBD2b set up. So I used a 97 OBD2a GSR ecu with my STOCK DX Harness. I wired up the Vtec Sel., Vtec Press. O2 Sen., and the Knock sen. Now I have no problems. Now if you want to use the P2T Si ecu it can be used. But if I were you I would go with a P28 and a Skunk2 jumper. I plan on buying a P28 here soon.

 

I also have a OBD2 GSR Harness for sale if you need it. Ill take $100 shipped for it.
