Ok, so in planning to get rid of an automatic trans for a manual in a 00 civic ex, I'm wondering if swapping the entire harness and ecu would be much more difficult than just "converting" the auto harness and ecu. I'd prefer going with a cleaner approach, hence the swap. I've never actually had to route a harness so I'm wondering how annoying it would be... and if it'd be more or less annoying than trying to make sure all the pins and sensor wires are correct to where they're supposed to be going. Any input?
