Hey i just got an msd 6AL ignition box for 20 bucks from a friend who just sold his 85 mustang(with a carb)...and mine is a 93 fuel injected...the question is with wiring...just hook up to coil/distr./battery or do i need an extra harness for my computer. And i want to buy a msd coil...is blater 2 good? and is a harness needed for that? thanks matt
