Hey, I have a 90 Civic Si. I did the auto to manyal swap. At first everything was out of whack until I put the manual transmission ECU in. That seemed to fix everything then one day my dad was driving it hard then a engine light came on. We got it home then found out it was the oxygen sensor. After switching it out for a new one it didn't help. We traced down the wiring and the wire snapped. I soldered it back togther and its been fine for a long time now. It has no insurance on it now so all I do is drive it around the property so it doesn't get out much. I got bored and wired up the reverse lights and they work fine but I moved one wire under the dash and now I'm getting code 17, vehicle speed sensor. I thought the wire I moved was a blank because of the automatic. I traced it down and it is a blank in the engine bay. Any help please, thanks Brad.
