i am trying to do a mini me swap on my 2000 CX. it sounds like the right way to do it is to get rid of my stock P2E ecu and go with the P2P out of the same year EX...how hard is it to do this(do i have to re-wire the whole car)? can i keep the same harness and just add the wires for vtec and the extra sensors? HELP...i understand how to do everything except this.
