How does the Rallye Dash Tach hookup?

67dart273 knows his electrical and I hope Im not speaking out of line, but he helps so many people and quite often they dont put in what they are working on, so it gets frustrating. I checked out mymopar.com for a schematic for your vehicle and couldnt find a tach listed. I did find 68 barracuda with a tach. Here are the 2 schematics for that.
