The signal wire... externally mounted coil...

I need to know, is the signal wire coming out of the black or grey connector on the coil, what color is the wire...?

Is there a wire _INSIDE_ the car that carries the tach signal through it? There were numerous black and wire wires at the harness under the pass.-dash... What about behind the cluster?

I need to get this thing hooked up, it's powered up, mounted and everything, I just need to get this last wire hooked up...

Thanks ahead of time...

Xeno,

The pink wire (not red) is larger than either of the black/white wires, and is the power wire to the HEI system. The 20 Ga. black/white wire is the TACH signal to the tach filter module. From the filter module it should be a 20 Ga. white wire until it hits the firewall bulkhead connector, where it again connects to a 22 Ga. white wire (circuit 121) all the way to the instrument panel connector. You should be able to find a filtered TACH signal there, on connector #11 of the 14-pin connector. If not, connect to the TACH terminal right on the distributor or '+' terminal of the ignition coil primary winding itself.

The installation instructions SHOULD have included all that....

 

it's a generic tach, I doubt they'd go through the trouble of finding all that info out on every car ever made...

Thanks, that helped alot... I found out where the signal is coming off the coil through some more searching. You say I should be able to pick up a tach signal behind the cluster on connector 11 of a 14 pin connector, it should be a white wire?

Thanks!
