i guess it depends on what brand of tach you get. mine has four wires(positive-red, negative-black, sender-green, then a white wire for the lights for the tach then two small wires that the instructions say you got to cut one if its a four cylinder. the small wires are brown and blue i think cut both for a v-8 brown for a six and the blue for a four. my tach is a autometer 5" monster tach phantom series with shift light.
i know what you are saying, but this kid bought only the shift light, not the tach. you know you can buy a shift light without a tach right? if you buy the autometer shift light without a tach, it only has three wires. thats what i have, because a big ass tach looks too ricey for me, so i only have the shift light. i just use the stock tach in the dash and i have a shift light mounted on the steering column. we are not talking about a tach and shift light combo, only a shift light.
