no you don't need to fix the reverse lights in order for the speedo to work. The speedometer plug is already on the transmission, your harness should have one that plugs in. If you've been driving and the speed isn't showing, if you know you've plugged it up, then your speed sensor is bad (happened to me). As far as the reverse light wiring goes. You WILL have to splice into some wires that come off the 'inhibitor switch'. I believe they're both green. Search man, its easily done good luck!
