Need help, MSD and factory tach

[Rizz67]

I had the same thing for my 67 mustang, I have a 6al, Blaster 2 coil and a Dist. all by MSD. You must by the tach adapter kit for it to work. Theres 2 models one for Magentic Pickup and other for standered firing, i have magnetic pickup. The adapter has several wires, white, which goes into the MSD box, black which is ground, purple which i didnt need to use, and red, which goes to the tach gauge. I extended the red wire so it could reach the inside. I sliced the black wire going into the tach, and sodered the red to it, you must have a complete connection to keep the circuit alive.(otherwise the car will not start) Which means the black wire must still be attached to the gauge,u just add the red wire to it.
