I have a CA18DET turbo motor in my pintara wagon and since installing this motor and 5 speed gearbox my speedo does'nt work. I was wondering if any wires from the speedo went into the old computer? if so witch ones?

try going to www.antrx.com, its a forum dedicated to pintaras, there is a guy there whose nick is aussie_gli, he might be able to help you out, as he plans on going ca18det into his pintara gli. he has a strong electronics background and he should be able to help you out with your speedo problem.

cheers.
