Alright i have searched and searched and i keep on getting diff answeres from people and i'm sick of it. A buddy of mine is putting in my h22a motor this weekend and he wants to know how to wire for vtec using the stock wiring harness. Is this even possible? Some sites tell me it is and others say no. so what is the real answer?
and if you can, how do you do it?

 

if the old motor was an h23, then yes you have to use the stock harness...look in the FAQ theres a thread on how to wire vtec...its got everything you need
