MSD 6-al On a 83 Ford with autometer tach.

I have a 83 ford f-150 4x4 with a card 300 6 cyl. I just got a new msd 6al box and a auto-meter tach but im not sure how to do the tach there is now loop to cut to run it on a 6cyl? and on the MSD I just need the wiring chart to make sure I hook it up right.
