I cant figure out where a couple of wires go. MSD 6010

Yellow Tach output - Do this go to the MSD box or My Tach on the dash?
Pink is for 12v source or ignition switch(same thing as 12v source).
Black is ground - ok to ground to block or intake?

On the back of my Autometer Ultra Tach it has spades connectors. One of them is SIG, does this go to the box or on the MSD harness?
Also on the Tach, one of the spade connectors says ground to Battery, can I ground it anywhere or does it need to go to the battery for ground?

Thanks

I ground to the intake, pink is 12 volts switched, the tach wire goes to whatever rpm measurement device you are using.

Sig is for the output of the msd(yellow) to make the tach get a signal. I ground my tachs wherever.
