I am installing a stock tach in my car, it is one that is a current sensing unit... I'm just making sure I am looking at my wiring diagram correctly, the tach is connected to a postive ignition source, then the only wire going to the postive post on the coil is from the tach terminal, right? Is a resistance wire still necessary? Thanks!

Sounds correct. There's a bullet connection about 8" from the keyed ignition switch on the dash (yours is in the steering column, right??), and the two tach wires plug into those. You can only do it one way (male to female, female to male). Yes, you still need the pink resistance wire. The whole thing is just plug and play. me check your shorts!
