i got a haynes manual, found the tachometer, but there were 3 different wires, tried em all, 2 of em when i connected the tach wire the needle jumped at that was it, didnt do anything. i looked at the wiring diagrams some more but couldnt find anything else for it, so now im stuck unless someone has put one in and knows what wire it is, thanks to you all for the help so far

don't look at where ford hooked their tach up, cuz christ knows what the hell they were doing.. find the part of the book that shows you how to install your coil, see which wire they say is the negative (or the ground) for the coil, and splice it to that.
