Hi Everyone,
I change my stock distributor with MSD Ready to Run Pro-Billet Distributor ( Mustangs Unlimited - The Premier Source for Mustang, Shelby and Cougar Parts and Accessories ).
Than my rally pack's tachometer does not work.
I send an email to MSD, i guess i need a adaptor.
But as i understand there are more then one ADAPTOR.
Who can help me which is the correct adaptor (Part # pls)
Regards

Hey Bud

Good Luck with getting the current sensing tach to work with that MSD dizzy, especially, if it's a multi-spark type. That being stated, call their tech line and ask for their recommendation.

Good Luck though!

what does your tach trigger off off??

I guess my aftermarket triggers off the coil so i don't see how changing the distributor would screw with it.....

I'm just a young'n though


but seriously...what does your tach trigger off of?

After looking at the dizzy, you might have something else, interceding, causing the tach not to function. That MSD dizzy, is just that a dizzy with a pointless trigger..
So, go back and check your connections.
