i had a sunpro tach and i stripped the engine over the winter and re built a bunch of stuff now my tach don't work? where do you hook up the wire on the distributor (where on the cap) i have an accell hei cap.
the tach trigger wire should be hooked up to the TACH terminal on the HEI cap, it is right next to the BATT terminal that you use to supply the 12v to the coil in the cap. Should be the green wire on the tach, red to 12v, black to ground, and white to 12v for the light.
