help with msd ignition

Recommended Posts

the car is a 72z with a 280 engine.

I have electronic ignition in the car now, and am adding a msd 6al box with a blaster 2 coil.

the challenge is in know how to hook it up to keep the old tach functioning.

MSD tech support suggested a 8910 tach adapter and sent me a diagram showing how to hook it up.

Does this thing work?

Any suggestions?

There is also a write-up in the Technical articles section as well:
