Negative Ignition coil wire color....

Hi,

I am trying to find the negative tach signal wire going into the two-wire plug off an ignition coil on the 5.2L V8 for a '93 Grand. It's the small 2-wire plug on the bottom of the coil. I can see a brown/white and a green/something wire going in to the plug.

I should probably test but I do not know how to!!!

Any help appreciated. Thanks in advance.

Regards,
Taki

Anyone know or ever tapped into this wire for their tach signal?

Thanks.

I usually trust the Tach in the dash.

On the ignition coil, the '93 FSM says you have 2 wires... a Gray with a White stripe and a Dark Green with a Black stripe. The Gray/White wire goes to the PCM and is labeled "Distributor Ignition Coil (-)" and the Dark Green/Black wire is the hot side, coming from the Automatic Shutdown Relay in the Power Distribution Center.

Thank you!!! I guess I was a little off with the colors. It is the Gray/White wire I am looking for!

Thanks.

What do you need another tach signal for?
