This is the readout part of the Dijitool, it has 4 lights and 6 setting, it is NOT connected to an ECU, it must be wired to an ECU.

the 4 lights are labled:  STR  FP  TPS  FI

the 6 place rotating selector knob has the words:

Temp !
Temp 2
O2
AFM
Batt
Pin19

It looks like this: http://www.loam.org/vw/Vanagon/DigiTool/  but mine has a round cable of hires and not the flat ribbon cable, the wires are connected to the tool, but not the ECU.

Should be worth $50 to $100, you can BID on it,  Over $50 and I'll pay postage to CDA and USA.
