Hello, I am wanting to hookup a pressure transducer to my Pro unit and have it be able to be easily removed from vehicle to vehicle as I use my interface on multiple vehicles. Since there is no 5v output on the EIO plug is there any way this can be easily accomplished? I am already using a portable 18v battery to power my wideband should I just tap power from there and use an inline resistor to drop down to the required 5v? The other 2 wires would just go to plugs 2 and 6 also, correct? Thanks
