Just tried hooking up my ScanGauge for the first time. I took it right out of the box, installed the Ethernet looking cable in the back of the ScanGauge, turned the ignition on but short of starting the truck, plugged the OBDII cable into the trucks ECM and nothing.
The backlight of the ScanGauge comes on (but goes out on its own) and nothing ever comes up on the display. No "connecting" nothing.
Anyone have this problem?
