[FireSale]

These units have indicator lights to let you know if they are firing correctly. I like having mine (version 8) in sight from the drivers seat and accessible for changing the rpm settings either by chips or dials. My distributor advance is locked out. I have one of the MSD Starter Saver boxes mounted to the backside of my glove box door. I can drop the door and see what it's up too, also.

But then I'm a hard core tinkerer...
