What goes into hooking up Hondata into a 4th gen prelude? Obviously the p13/p14 cannot be used, so a Civic or Integra ecu must be used. But, what about the wiring? Is it difficult rewiring the harness/pins to get the ECU to work? What exactly does this entail?

 

As far as I know all OBDI Honda VTEC equipped ECU's plug into eachothers harnesses. I don't think you'll need to worry about any wiring. Just buy some integra/civic OBDI ecu and have it chipped and plug it in.

 

if u have OBDI wiring, u can easily use a p28 or p72...depending on what u intend to run...turbo/na etc..
