We need to know the year/make/model of the vehicle before we can help you.. Also assuming you mean the tach wire?

tach wire, not tech wire. and yes those are the right wires listed. take a multimeter and set it on AC voltage. put your ground test lead on the + battery post and take the positive test lead to the wire you suspect to be the tach wire. it should read about 1 to 6 volts AC, and increase voltage when the engine is revved.
