I want to hook up my repro/stock tach in my '69 which has never been hooked up because I had an Autometer in the car that's gone now. I have a MSD 6AL ignition box, MSD distributor and MSD coil in the car. I don't want to fry anything so I need some clarity how to get it working properly. Am I using the stock wiring from the harness (fork connector with 2 wires, another fork connector with one wire) that hang by the wiper motor to connect to coil? There is talk about some filter for the tach, is there a filter in this tach? YES or no? MSD says connect gray wire from ign box to somewhere which I don't know where! So what I need to know is: am I simply hooking up stock wires to coil from harness to make it work? IF that doesn't work am I using the gray wire from the MSD box to get the tach to work and where does that wire go, and what about this "tach filter? MSD's instruction booklet for the 6AL box says "bypass in-line filter. Thank you for any help
