iam gettin a jdm itr swap obd-2 into my obd-1 how do i change it any pics.

 

Buy an OBDI to OBDII jumper harness and an OBDII charcoal canister(There's an extra emissions sensor mounted on the fuel rail of OBDII cars that has a vaccuum line running to the charcoal canister, OBDI canisters don't have the extra nipple for this sensor). It's easier to just buy an OBDII B16/B18C harness, but you can cut/splice your old harness.

If I were you, i'd run a chipped OBDI ecu.
