I have a 1993 DX just dropped the EX/Si Z6 in and i want to know how to hook up the vtec. I am still using the old non-VTEC harness, I want to know how to wire it in using minimal money and time. I also want to know what other parts do i need to complete the swap. I heard that i need a p28 ecu and if so which is good and would it be a good idea to get a chipped one

Please help!!!!!
