help with msd ignition

[pastor.rev.it]

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?

thanks

First, notice that you posted this in the 240K forum, not the 240Z forum.

Second, there have been lots of threads on this subject. You might want to try a search, I searched for 'msd 6al' and got these relevant threads:

If wired in correctly, the tach adapter works like a charm, it even smoothes out the tach pulses, so a previously erratic tach will now function beautifuly.

Its really not that hard to put this sort of thing in the Z section, considering it makes up more that 75% of the forums...

Thanks for the help.
