werd, i have it wired to the 24 pin connecter on the white wire (rpm read out) i tapped into that wire. There are adjustments on the gauge for 4, 6 and 8 cylinder engines, i have it set to 4 cylinders. still only half the reading. Trying to figure it out
once i get time, ill try to wire it to the white wire in the bay near the intake manifold like endless posted.
