I did the swap like 3 months ago and have been living with bogging for that long since i still have the AODE computer. Now i want to switch it to a 5 speed computer, do i need to have the 5 speed wiring harness for the speedo to work, im not to concerned about having a reverse light (even though i know its probably a good thing to have). i been running without a neutral safety switch too, that i dont really care about though, i push the clutch in out of force-of-habit anyway. Oh ya, will the car even start with the 5 speed computer if i dont have the harness?
