tachometer help

[CAE79]

I have a 1985 Ford Bronco 351. How do you connect a tachometer? The gauge works fine. I would like to know where the wires connect to. Any suggestions would be helpful. Thanks.

Are you talking about the engine compartment end? If so, the dark green with yellow dashes connects to the ignitioncoil (-) side and the black with light green dashes connects to the distributor ground. Both connections are via connector C323 that is between the ignition module and the distributor. Also you need to check fuse 18.

Good luck,
