Re: tach question

Your tach should have 3 wires... 12v, ground, and signal...
I assume the signal wire is the one you are asking about... it should go to the TACH terminal on your distributor if you have an HEI...

Re: tach question

just put one in myself two days ago.
green when to distributor.
black is ground.
red i put into fuse panel
and the white....
well i put it into a 5 amp instrument light part of fuse panel. and then fuse blew...so i ended up with no lights on the inside of truck.
i replaced the fuse. but not connected the white anywhere yet.
not sure if i can put a bigger fuse instead of the 5 amp. and be ok.

hope that helps.

Re: tach question

The terminal is with all the others on the underside of the tach - just go up from underneath and you will find it. Its location is printed on the coil cover.
