end to the control box mounting location.
WHITE\GREEN wire to INDICATOR CIRCUIT
WHITE\BLACK wire to CHASSIS GROUND
6. This system has two options for the included LED indicators. You can have the indicators
located in the face of your new VHX display, and/or use the additional lights in your vehicle’s
stock locations. To use the new in-face indicators, follow the wiring instructions found in the
main VHX manual.
The optional indicator lights in the stock locations may be used by plugging the eight included
indicator harnesses into the receptacles on the lower back of the VHX system. Do not wire
these to the VHX control box:

7. Using the four original mounting screws, fasten the VHX display into the dash.
8. Reassemble the dash in reverse order. Refer to the main VHX manual for control box wiring
and setup instructions.
9. Stock 3-Wire alternators may need an additional wiring connection at the gauge cluster
connector. You will need to add resistance from the Red/LT GRN wire in the 12th pin location
to the LT GRN/RED wire in the 11th pin location. This will ‘excite’ the alternator telling it to
begin charging. This can be done using the included alternator load harness.
