hey guys a few quick questions. first. will the engine harness from a b16a1 fit on my ls firewall harness. do i need to modify anything to plug and play the ecu? i had a vtec prior to this swap but, i just used my ls ecu and a activation switch. so im gonna do it right now. i just need more info on wiring this swap. i dont know what wires to modify, if i have to at all. thanx in advance
