the prelude harness does not fit the accord body, not supposed to.
on my 4th gen the harness fit near perfect. i had to add the 2 wires and a ground for vtec, had to switch 2 plugs for oil pressure sensor and EGR lift sensor, then add a pair of wires for the IAB (ff2a6 has this already though)

total time to wire it up...1 hour.
