You have a 98' which is obd2a.


Did yo change any "under the dash wiring"? Edit: It dawned on me that you have a 98' (obd2a)and you plugged in a p2t which is from the 99-00 si (obd2b).

If you didnt then you should have run a obd2a p72 gsr ecu. Which is in the 96' -00' gsr's.
You should still have 3 Seperate Plugs.

Here is some different jumper harnesses. All of them have 3 Plugs.

you need to use a 96-98 engine harness instead of the 99-00 one that you have because on the 99-00 the 3rd plug the one your missing is part of the body harness that goes behind the dash . for the B16A2 99-00 you have to either use the 96-98 mod it and repin the ECU for OBD2b or get a jumper harness or swap out the rest of the car harness from the 99-00 car.

if you are gonna go that far, I would just swap the entire car over to obd1 and run a p30 ecu...easier to tune, and obd2 sucks ass...but thats just me


you could have just used your stock D series 96-98 harness and gotten a obd2a to obd2b conversion harness from boomslang..then you can run the p2t and everything would work.
