tach signal
I have a 454 tbi engine.The coil is a little different from what i am used to.It has two plugs on top with two wires running from each of the plugs.One is red and the other is white.I cant figure out ...

Red should go to a 12 volt power source that comes on with the ignition
Black should go to chassis ground
Green need to go to the negative side of the coil
ONLY the green wire goes to the coil!
