| Hi
 
I am thinking of fitting a cigar lighter to my BJ8 so I can charge my  mobile 
phone, and run a TomTom SatNav off it as well.
 
My BJ8 has the original wiring set up.
 
My question is: 
 
for devices that run off a cigar lighter like phone chargers and power  
converters for things like SatNav, does it matter whether the car is positive 
or  
negative earth?
 
Thanks in advance for all the help I know i will get.
