All after market tach's aka moster tach either have2 loops of wires hanging out instructions tell you by default it is set for 8cyl, cut 1 of them for 6 cyl, and both for 4cyl. My monster Tach is set electronically, To cahnge it to to either 4,6,8, or 10 I have to hold a button on it while turning the key on and then hit the button til the tach reads the number of cyl I have, just do a search on the internet for instructions, I had a cheaper tach from autozone it had a switch on the front for 4, 6, or 8 </P>

Trust me all, You need the speedo head only, After you take the cover off the cluster it seperates into 4 sections, volt&amp;temp, tach, speedo,fuel&amp;oil just change the speedo section, I have done this myself, and I am a ASE certifed mechanic,been working on fords for 18years,and I have owed over 25 79 and newer mustangs, i have made just about every combination and know what works, also about the speedo, it will be accurate, if it is off, it was off before or you got a bad speedo, because if you put wrong size tires or differnt gears you are not off by 3to5 miles you would be off by a % therfore faster you go the more you are off. But a speedo is a speedo.

it is easy to do
