Hey everyone, i'm new to this site but have a few questions to ask. I did a swap and i am using a an obd2b - obd1 conversion harness with a 95 p72 ecu. Now My question is do I have to rewire anything or should everything be plug 'n Play(i.e. vtec )? If I do have to rewire sumpthin Can somebody tell what it is I need to do? I dont need to hook up IAB's cuz I just installed a Skunk2 Intake Manifold. That should eliminate the secondaries. all im concerned about is getting the vtec to engage. Any helpful replies will greatly appreciated.
