cant argue with the original dissy but if you want electronics then you must upgrade the electrics to suit and its all about a smooth constant supply and absolutely as near as perfect earths .Your cars wiring system was designed 30years before transistors and now you want to enter the space age . It can be done and is often quite successful ; Dig deep into all the installation paperwork you can find, for whatever system you choose [IE not listed with but required by mallory a 611 power cell and the inline power filter ]. Most failures can be traced to ether wear in a related component [dissy cam lobes] or incorrect install .Even something as simple as connecting an earth or power in the wrong spot can reek havoc ,read the directions 3 times/ think and then reread then if any doubts contact the manufacturer most are more than willing to help
