I have a 2000 Honda Civic EX. I am wanting to swap the automatic transmission with a 5 speed transmission from a 2000 civic hatchback. Will I have to swap the ECU or can I just cut the extra wires going to the auto tranny? Will the wiring harness outside of the firewall be the same for the 5 speed and the auto or am I going to need a completely different harness?
