Re: HEI vs Sunpro tach install?????
Most tachometers have 4 wires, ground (black) , 12V (red), light (white) and tach (green). Like BB73 mentioned the green tach wire goes to the spare terminal on the cap. It will actually say battery on one and tach on the other.
As far as placement goes just put it where you can best see it. Guage pods are fairly cheap and very visible when mounted to the piliar.
