The VCM-100 is designed to work with Drive by Wire applications utilizing OBDII, Custom CAN bus and signal inputs.
The VCM-200 and VCM-300 are Drive by Cable add on modules to operate a cable operated carburetor or throttle body
•
Works with OBDII CAN connection for speed and tach data, or discrete wire inputs.
•
Custom CAN speed and tach data defaults to 2008 and newer GM CAN bus engine/drivetrain packages with US
SAE code. Using the Dakota Digital wireless application, (for Android or Apple), the CAN bus can be set up for
almost any CAN bus interface.
•
Works with a variety of pre-programmed EFI interface modules that supply speed and tach data, but can be
configured for others that provide the needed data over a CAN bus connection.
•
Can be used with most OEM pedals for US GM, Ford and Mopar cars.
•
Can use one of the available handles for purchase from Dakota Digital or learn a variety of OEM handles for
controlling the cruise operation.
•
USB port for field upgradable software.
•
Built in selectable load for the brake input for use with LED tail lights.
•
Seven segment display and setup switch can be used to configure most options. All options can be configured
through the Dakota Digital wireless application which can be installed on most phones and tablets.
•
The wireless application allows for a manual setup process, or the step-by-step Setup Wizard may be used.

It is set to use the OBDII port for speed data, and the tach and clutch inputs are disabled. It defaults to using the Dakota Digital HND-2 switch.
- Page 4 INITIAL INSTALL AND WIRING 1. Mounting – the VCM-100 must be mounted inside the vehicle and NOT in the engine bay. 2. Determine if you will be using DBW (drive by wire) or DBC (drive by cable). DBC is used when you have a mechanical linkage to your throttle body and have the secondary cable module.

Page 5: Connectors And Pin Outs
CONNECTORS AND PIN OUTS The VCM-100 has 3 connectors and 15 screw terminals. OBDII CABLE connector is for the OBDII/CAN bus cable, PEDAL CABLE connector is for the pedal harness and DBC CABLE connector is the interface to the mechanical cable drive module. - Page 6 The setup switch on the side may be used to put the VCM into setup mode. Most setup can be done using the switch and seven segment display. All options can be setup using the Dakota Digital app for phones and tablets.
- Page 7 Cruise Indicator Cruise Indicator: The “INDICATOR” output produces a negative trigger to operate the cruise indicator on a Dakota Digital VFD3, VHX, HDX, RTX or Grafix dash system. The “INDICATOR” out will connect to the “CRUISE” terminal on these control boxes.
- Page 8 In some cases, the CAN High + and CAN Low - wires could be soldered direct to the OBDII harness. This will allow for the OBDII port to remain open, or be used by a Dakota Digital BIM-01-2. SAE CAN bus uses pins 6 and 14.

- Page 10 Cold Side Brake Wiring LED brake Lights When using LED brake lights, the above wiring will need an option changed in setup. The menu option of is normally set to for incandescent bulbs. This needs to be changed to for LED brake lights. This will bypass a safety mechanism that only allows the cruise to engage when it sees ground from the light bulb wiring.
- Page 11 Handle Wiring HND-1 or HND-3 The HND-1 and HND-3 switch handles will come with a connector and pins on the wires. The connectors will not be used with the VCM cruise module. Cut the pins off of the wires and strip them back approximately ¼ inch to be inserted into the screw terminals on the VCM.
- Page 12 Ford vehicles. To use these switches, you must do a switch learn procedure which can only be done through the Dakota Digital application for your phone or tablet. You must find out which wires are the power wires; we will learn the button operation.
- Page 13 Throttle Pedal Harness There are pedal harnesses available for Drive-By-GM, Ford and Mopar applications. The throttle pedal harnesses are a plug and play style. The connectors must be the proper mating connector and wiring for the pedal used. The image below shows connections for the GM pedal harness. Ford/Mopar wire colors may vary. [13] MAN #650847B...
- Page 14 Certain models of pedal require pins B and E to be reversed. If necessary, the 394309-06 crossover harness is included for this purpose. If the display flashes an E4 error after learning pedal voltages, or if the Dakota Digital app requests that the crossover harness be installed, please install it between the VCM and the 8-way connector on the end of the pedal harness.
- Page 15 Tach Signal Wiring If not using the OBDII or CAN bus for Tach data you can connect a tach signal from a gasoline engine to the “TACH” input. When using this input, you will need to go into setup and select the signal input type. If the signal type is SIG for a tach wire connecting to the VCM, select the proper cylinder count from the options of: 4, 6, 8, 10, and 12.
