I just completed a b16a swap in my 91 crx si, and i've been having trouble on finding out how to make my vtec work. the wire on my vtec solenoid isn't hooked up to anything and this other plug right next to the distributor cap isn't plugged in too. i plugged everything else from the stock si wiring harness to the b16 and those where the only two that weren't plugged in. i was wondering if anyone of you guys out there can help me solve this problem so i can drive the motor to it's full stock potential. the ecu if have is obd-1 i beleive, it's on the first gen siR. and i also have another problem. my right axle (shotgun side) is locked up. someone told me to remove the dust pan and that will solve my problem. can someone clarify that for me or do i have to get a new right axle.

 

If you do a search on B16 you will find tons of information. You actually are missing four wires. O2, Vtec oil pressure, Vtec selonoid, and knock sensor.

You will also be able to find info on the dust boot in that same search.

Good luck.

 

look on the stock wiring haness off the B16. find the plugs for the vtec and the second o2 cut them off and add them stright to the ecu.
