I swapped a b16a (obd1) jdm motor into a 98 hatch (obd2) everythings close to being done i just wanted to know about the map sensor. I have a plug for it on the harness but my throttle body does not have one on top like the b16a2 does .. do i need to run this plug or can i just leave it be???

 

see if you can't source a obd2 TB off the Si and i think the coolent lines will need to be changed aswell.
