I am hooking up an MSD 6AL to a stock DJet distributor. Which tach adapter? Anyone know the diagram pages for the installation manual that apply? Yes, I have done a search (IMG:style_emoticons/default/biggrin.gif)

Rob and I went the simple route (I subscribe to the KISS method when possible) and hooked the tach wire to the "Tach Output" on the back of the MSD box.
I will admit I cheated and read the instructions for the MSD where is says: "The MSD Ignition features a Tach Output Terminal on the side of the unit. This terminal provides a trigger signal for tachometers, a shift light or other add-on rpm activated devices. The Tach Output Terminal produces a 12 volt square wave signal with a 20% duty cycle."
