k i got a question... the instruction is easy for the apex vafcII... but my question is.. you know the VTM signal wire we have to cut it??.. and the wire going to the ecu.. thats the wire we hoooked up the blue wire from the vafc.... what about the wire going out to the engine??? isn't it the vtec oil pressure switch??? oh and by the way its for my lsvtec with a P73 chipped ECU.. Thanks and just wondering if we have to hook up the VTM from the engine or just leave it hanging???? thanks agen! :)
