Hello folks, long time no visit, my bad. We have been working our guts out getting some conversions done, and have three mostly completed with two more in the pipeline. First delivery is taking place this weekend, and im racking my brain trying to get the tach. hooked up. Called dakota digital today, not much definitive help. Bought a factory d50 with 4d55 for reference, figured out how to make that tach stop working by disconnecting sensor on back of fuel pump. Also isolated tach wire on the gas factory montero, that works and stops on command. Now how do i get the diesel output to work with the gasoline tach! ARGH......if my hair was longer id pull it. I looked in the archive, and found nothing relevant, but maybe i was looking cross eyed...any help would be, um....er....helpful? anyone done this? Anyone have wire schematic for the d50 tach power supply and such? anyone know the meaning of life? Please help me before i give up and do somethign stupid like buy a new tach and spend a bunch of money i dont need to.... <img src="/forums/images/graemlins/confused.gif" alt="" />
