How to hook up a DataQ to the PLX?

[Phoenix]

Anyone got a diagram about for this , this is off SHONUTs site : For a PLX WB, connect the black PLX wire to the ground terminal on the DataQ (as well as your power ground), and connect the white wire to Channel 1 on the DataQ.


Im specially intrigued by the statement in bold

I think he meant to say battery positive. Looks like he's using the same ground for the PLX and Dataq, using a different ground may show different readings. I need to hook my dataq up for fuel pressure, haven't had a chance, I'm using the DIYWB for my PLX wideband.

Battery negative! Don't hook up the positive to that. Power ground = negative battery terminal.
