also there is a sensor on the power steering line, does that plug in to anything now?
 
if your car is wired for 0bd2 and your engine is obd1 you have to change your harness to obd1 also.

no he dosent, since your car is a 99 ex u can use your obd2 harness all u need to do is get a 99-00 si dizzy and will plug into your wire harness, u will need to take out stuff from your old single cam motor such as injectors,iacv, and that should be it, but u will need a 99-00 gsr or ls altanator as well.
 
the problem (i think) is its OBD2A to OBD2B and the plug for the dizzy does not match up from the EX one.

"Yea you have to use the plug from the d16 dizzy on the b18c dizzy. you will end up with extra wires, the obd2a b18c dizzy has a extra wire for the tach reference that you dont need"
so basicly what i've gathered is that i need to take the harness off the d16 dizzy and put it on the b18c dizzy.
sound correct to people?
