I'm planning on installing an MSD 6A, but after reading through msd's instructions online, I'm still not sure on how you use a tach along with the msd box. I'm running a pertronix ignitor in the dist and an autogage tach. They say that I would need the tach adapter 8910. The wiring diagrams show how to wire this in, but then don't show where you connect the tach. I'm sure someone here has done this install before. Just wanna make sure I got everything planned out before I start buying stuff. Thanks in advance for the help.
