more specifically... a b18b where a y7 used to be. i don't believe i'll have to do much wiring because they're both non-vtec.... but the b18 is an obd2b motor. in my internet searching it seems like i can just get the conversion harness and run the obd2b ecu, but will i have to run any extra sensors on top of that? can i just run an obd2a LS ecu and not have to worry about any loose sensors?
