MSD Tach Adapter
When installing an MSD ignition control on your 1979-1985 Mustang and the tachometer, fuel pump relay, and electronic fuel injection isn't working, you may need an MSD tach adapter. This is due to the trigger signal not being strong enough to trigger both the MSD and the factory's components. This adapter is a quick and easy to wire in and will have your tachometer working great again! The PN 8920 will correct the operation of most voltage-triggered tachometers that do not work directly off the tach output terminal of the MSD Control. This Adapter should also be used on current-triggered tachs (hooked in series with the ignition switch).

Testimonial: The best company I have ever dealt with
LRS hands down is doing everything right. Every experience I have ever had with them shows just what an amazing company they are. There is a reason I come back time after time, instead of going to those "other" mustang aftermarket websites. Customer service is the name of their game, and they are winning. It does not matter whether you call, email, forum PM, or go to the actual store, they are always incredibly helpful and enthusiastic. (Getting to see the Cobra R in their showroom was awesome). I'm proud to have the LRS windshield banner on my car, because I know they will always have my back.
