b16 vtec probem

i have a 89 crx si with a b16 1st gen bottom and a second gen top and my ecu was taken out to use on a different car. i have a skunk2 chip so my vtec kicks in at 4200rpm. when i took my ecu out and plugged it back in a wire got loose and i dont know where the vtec wire goes. my check engine light now comes on and my vtec does not kick in. so will someone help me out. thanks

Pin A8 is for vtec solenoid, Pin B5 is for the vtec oil pressure switch. this site shows where the pins are located on the ecu.http://www.geocities.com/b16aprelude/hondaengines.html
