swaping a Z6 into my 92 VX. I know its got vtec-E. What & how do i do any other wiring changes using my stock harness? I notice that my Vx has a 5wire o2 & i've heard the Z6 runs with a 4wire o2. What needs to be spliced or tapped for changing the oxygen sensor from 5wire to 4wire? Do any other things need to be added on, or left of? The Z6 doesn't have a knock sensor, what about EGR? I'll be buying a P28 from the junkyard,which plugs directly into my existing vx harness(correct?) thanks for any usefull info, i'm not a wiring champ- bolt ons are cake.
