Is this the right engine harness
well it looks like it's definitely for a 99-00 Civic based on the 3 plugs and the firewall grommet. Other than that it's hard to say whether it's really a Si or not
So Im guessing your planning on changing out your wire harnesses. Are you removing your B16 or leaving it in to do the switch? Since your buying a new harness, Im guessing you tried to rewire your dizzy plug and it did not work?!?
