Wiring q's

Hey, i need a lil help with my tach, I know what wire goes 2 what, but I need help with hookin it up

What wire can I tie my POWER(red) wire in to so it only works when the key in ON?
Does the TACH(green) go to the neg side of the coil?
what wire do I tie my LIGHT(white) wire in to so that the tach lights up with my dash??
As for the GROUND(black) wire, can it be a chassis GROUND, or does it have to be direct to the negative of the battery??

THANX yall

Red Power to the 3-way yellow connector behind the instrument cluster.

see the Radio thread

Green wire to neg side of coil.
On the horseshoe connector attached to the coil ...it says TACH right on it.

The white wire gets spliced into the blue/red striped wire behind the instrument cluster or down near the headlight switch.

Ground wire

I don't know where you are installing the tach but anywhere there is metal on the dash or the bracket behind it is good.

~~~~~~~~~~~~~~~~~~~~~~

In my earlier reply,.

I stated : See the RADIO thread.
https://www.ford-trucks.com/forums/5...placement.html
There is a picture of it on it
at that time it was 2 threads from this one.

Now it is on page 2.

Maybe from too many Non-73-79 topics ?
