I have a 95 Buick Roadmaster 350 2 Wheel Drive. I put a new transmission in it but the speedometer dont work. The car does not have a Distributor or a coil. Instead it has a Crank Trigger in the front. All of the Spark plug wires go from the spark plugs themselves and go around to the front of the motor right above the Crankshaft Pulley. So my question is this: How do I hook up a Tachometer (rpm) if it does not have a Distributor or a Coil?
