VHX-68C-CVL

Dakota Digital VHX Instrument Installation

For 1968 Chevelle/El Camino Systems

Your new VHX-68C-CVL kit should include:

Installation

1. Remove the stock instrument cluster/dash bezel from the car.

2. Remove the five screws holding the gauges to the bezel as well as the two screws holding

ground straps on the back of the system. Save the screws as they will be reused to secure the

new VHX system in the steps below.

3. Remove the stock gauges from the stock lens spacer. The lens spacer is going to be reused to

secure the new VHX gauges to the dash/bezel. Remove seven screws holding the gauges to the

spacer. Save the screws, they will be reused to attach the new VHX system.

Manual # 650347

4. Remove the stock lenses from the lens

spacer by removing three screws from the

front of each lens. The stock lenses are

removed since the new VHX kit features a

hard coated clear lens. Now is a good time

to clean the stock lens spacer as it is reused

to secure and space the new VHX system.

5. This step is optional for automatic transmission bezels only. If you purchased a separate GSS-

2000 kit from Dakota Digital, the gear position can be displayed in the VHX message centers,

therefore the stock gear position indicator can be removed.

The stock gear position indicator will slide out from its location. Remove the protective film from

the supplied block off and align the notches with the bumps in the stock housing. Use silicone or

hot glue to attach the block off.

*** Allow the glue to dry before continuing with the installation.

6. Remove the protective tape from the clear lenses and install the VHX system onto the stock lens

spacer removed previously. Secure the system to the spacer reusing the seven screws removed

in step 3.

The spacer

will be reused

Manual # 650347

7. Secure the VHX system onto the bezel with the five screws that were removed in step 2.

8. Connect the short CAT5 cable between the two gauge housings, then connect the long cable to

the system so it can be routed and connected to the control box as the system is re-installed.

9. Re-install the cluster into the car and refer to the main manual for wiring instructions to complete

the VHX installation.

MAN 650314:D

Thank you for purchasing a VHX system from DAKOTA DIGITAL. VHX is a loose

acronym for Vehicle Hybrid Instrument Systems. Representing the latest electronic dashboard

technology for the street rodder, car, and truck enthusiast alike, the VHX system combines

modern digital electronics with a traditional look to give the driver up-to-date and accurate

information on the operation of his or her vehicle. Fully lit needles, backlit faces, and highly

visible LCD message centers are a few features that make the VHX lineup stand out from other

aftermarket instrumentation. The VHX system boasts excellent daytime visibility and while under

computer control, fully backlit and dimmable for nighttime driving. Monitoring solid state sensors

with microprocessor technology and driving precision stepper motors, the VHX dashboard gives

the driver unparalleled accuracy. User-customizable display feedback and additional features not

typically found on any other brand or type of instrumentation are standard in the VHX system.

Digital accuracy and solid state reliability will give you, the driver, quality service for miles down

the road that includes a limited lifetime warranty on a product engineered and manufactured in

the USA!

WARNING

These are precision instruments and must be handled with care. Do not disassemble gauges.

CARE AND CLEANING

Never open the system or attempt to remove the needles as the calibration of the

instrument system could be thrown off. All systems are calibrated and tested before they

leave Dakota Digital.

The clear lens on the front of the VHX system can be cleaned with a mild soap and water

solution or common glass cleaners. Use a soft cloth such as a micro-fiber for wiping the lens

clean.

MOUNTING SYSTEMS

Most VHX systems and kits will come with a separate instruction sheet with mounting

details. Follow this sheet for mounting the actual display system in the dash, and then refer to

this manual for wiring and operation instructions.

CONTROL BOX MOUNTING

Once the display panel is in place, mount the control box within reach of the supplied

networking cable (approximately three (3) feet). If a longer cable is required, replacement CAT5

cables are available online as well as your local electronics stores. Choose a mounting location

that will allow you access to wire all of the inputs on either side of the control box. Double sided

tape, hook and loop fasteners or screws in the two tabs on the case work fine for securing the

control box under the dash.

When selecting a mounting location, avoid placing the control module next to, or

just opposite of the firewall from, ignition components, i.e.: Ignition coil, HEI, etc. Ignition

components can emit tremendous amounts of electrical noise, affecting the operation of

electrical components which can cause erratic operation.

***If you are purchasing a longer network cable to connect the display system to the

control box please make sure to get a CAT 5, CAT5E, or CAT6 “patch cable” and NOT a

“cross over” cable. Replacement cable should be seven feet or less.

WIRING

While the control box contains several connections, the wiring is straightforward.

Depending on how many auxiliary functions you want displayed, not every terminal will be used in

most applications. On the pages that follow, we describe the function of each terminal, what they

do, and how to wire them.

STATUS LED

This LED is located at the corner of the control box, next to the GROUND terminal. The

LED is used for diagnostics and for a quick visual check if power is present.

•A steady flash, on and off, about twice a second indicates the system is powered and

operating normally.

•On steady indicates low power, below 9V, at the POWER terminals, or that the system is

in DEMO mode.

•A short flash once every four seconds indicates the CONSTANT POWER terminal is

powered and the system is in stand-by mode.

•Not flashing or lighting indicates loss of power or ground.

GROUND

This is the main ground for the display system. A wire should be run from this terminal to

the vehicle’s main chassis ground. Use 18 AWG or larger wire to ensure sufficient grounding.

Proper vehicle grounding is extremely important for any gauge (or electronics) to operate

correctly. The engine block should have heavy ground cables to the battery, frame, firewall, and

body. Failure to properly ground the engine block or the control box can cause incorrect

or erratic operation.

CONST. POWER

Connect the CONST. POWER terminal to a +12V power from the fuse panel that is “hot”

all of the time, or a fussed wire (5-20 amp) direct to battery power. This terminal should have

power all of the time. The constant +12V supply source should be a fused 5 - 20 amp circuit, the

system draws less than 1 amp, so sharing an existing constant power circuit will generally be fine.

Use 18 AWG wire to ensure the system receives a sufficient power feed. This terminal keeps the

clock memory as well as returning the needles to zero when the system is shut off.
