Hey everyone,
I just purchased one of these. It is the type that doesn't utilize a gauge and instead reads through laptop computer via the PowerLogger. The wiring diagram seems fairly simple with the basic power and ground, two wires to PowerLogger itself and then there's a gray wire that is supposed to connect to the computer, but it's an open wire. The instructions state it goes to a serial port, but I don't understand how this works with computers that don't have the pictured serial ports. (My laptop has only USB).

I'm sure a few people here are using this wideband, so if you don't mind, could you help me with this information? Thank you.
 
Eric,
Can the brown wire be grounded to the PL input ground?
