 Berry Pinney, owner/manager has been dabbling in electronics since he was a kid and went on to make a living out of it.  He worked on the wiring on his first car, a 1956 Chevy and installed a Holley Fuel Injection system on his first Corvette in 1995.  But, things have changed a little since then...
