[rex187]

hi. this is my first time to about about any thing on hondaswap.com. anyway back to my question. i have a 91 crx si and im doing a b16a1 swap in to it. i was wondering what the hasport sub harness was for and is it like a conversion type thing?

the subharness is the harness in your engine bay that has wires for vtec, knock sensor, 4-wire o2 sensor, it is a harness that connects the ecu adapter to the engine componets.
