Air Pressure gauges

Hey guys,
Just wanting to know if there are any "electric" air pressure gauges, apart from those dakota digital quad ones. I mean ones that have pressure senders and then just require a few wires to be run to the back of the gauge, not a whole length of air line. 
 
Reason being is I planned to mount my gauge (only running front and back)  in the ashtray of my car, UCF1X. Problem is that all the mechanical type gauges require air lines to be run directly to the back of the gauges and there is no room for that if I mount them there. 
 
Any input would be greatly appreciated.
