MSD 6A work with tach?

Well, I'm about to make the MSD plunge and buy a 6A and blaster 2. One question, will my autometer 2 5/8 tach work with the 6A's multi-spark stuff?

Thanks!

I have a MSD 6T and it has a connection just for the tach. It doesn't hook to the coil anymore.

[updated:LAST EDITED ON 22-Aug-02 AT 08:48 AM (EST)]Doh! Your right! I just looked at the online istall instructions and the 6A is labelled as having a tach output!
Thanks for putting my mind at ease!

My ignition module has really been acting up lately, so I can't wait to put in the 6A!

Thanks again,
Matt

EDIT- Where did you mount your 6T? In the stock location? I figured that would be easiest/look the best. It is a long trip to the battery from there though. Did you take your ground right to the battery per the instructions?

DO NOT HOOK MSD IGNITION TO THE COIL

20 sparks per cylinder*3000RPM= makes your tach think the engine is spinning 60,000RPM they have a special hookup for using a tach . I just ran a wire under the back lip of the cowl from the box across to a hole in the firewall for access to the cab (see sig pic)

Yeah, and the MSD will actually work will more tachs than it says it will. I have a Sunpro gage, MSD says it needs an adapter, but it works great plugged in to the tach output. I've checked it with several other devices, and it's extremely accurate.
