I think you posted about this already but im to lazy to check. Umm well yeah everything should work fine with that ECU but just because he is getting the obd2b-obd1 harness does'nt mean your whole car is converted to OBD1. I have not done a swap into a 2000 but I do know that everything will not plug right up. Im sure there are 2 plugs that need to be extended. And a few other issues but other then that the swap is easy.
