I just got a pyrometer guage off craigslist and it did not come with the probe that hooks up to exhaust manifold. But i now the red and yellow wire hook up to the probe and you also hook up the yellow wire to transmisson plug right? The yellow wire hooks up to the 12 or s on the guage and the red to the 04 or the i on the guage right? And the red and black wire at the bottom of the guage are for the 12volt and ground?
