I have a MSD ignition box and tach adapter that I had on my old '01 dodge ram. I had bought them because I wanted the box but the guy already had the tach adapter with it and all wired up to plug right into the factory harness. Now I am putting it on my TBI454 along with my Pro billet distributor and MSD coil. I was wanting to know what does the tach adapter do and is it needed? Also anyone know how to hook this stuff up?
