How do you install a aftermarket tachometer on a 1992 Mazda B2600I 2.6L 4x4 when there is no factory tachometer?

You will need to connect the tach to a ground and +12v source, the signal wire will have to be connected to the ground on the coil. Since the truck is fuel injected, you will likely have to find a way to wire it in with the connector on the coil.
