your car's harness is obd2a. if you want to use the obd1 ecu you'll need to get an obd2a-obd1 conversion harness. i tell everyone to get them from www.boomslang.us because i've never seen one fail. stay away from the skunk2 harness (everything else they sell/make is great, but they don't make their own conversion harnesses) and the jdm**** brand conversion harnesses...i've seen way too many failures even brand new.

the obd1 ecu is tuneable when chipped, but you won't pass emissions w/ the obd1 ecu because obd2 emissions is done by plugging into the data port and it won't read w/ the obd1 ecu. basically in an obd2 car you have to have the obd2 ecu w/ no check engine lights or stored codes. that's how you pass...if you know what i mean.
