This manual covers the aspects of installation, operation, and troubleshooting of the CRC-1000 “Drive-by-Wire” cruise control. The CRC-1000 was designed to work with CAN bus GM LS engine/drivetrain packages, as either a complete transplant from a stock vehicle, or a Connect Cruise, using a GM ECU programmed with US SAE code. -
Page 2: Parts List
Pedals vary in build and operation. The pin layout must be a single row as shown in the purple pedal plug of the 250-2766 below. If the pins are turned, or the pedal has a dual row of pins, the CRC-1000 will not function, and the wiring and cannot be modified “to make work”. -
Page 3: Connectors And Pin Outs
CONNECTORS AND PIN OUTS The CRC-1000 has four connectors on the front that we use. They are labeled as: • J1 – OBDII cable • J2 – Power/Ground/Input harness • J3 – Handle/Switch harness • J4 – Pedal harness The small connector in the back is not used, but there is a small cutaway for an LED, that can used to observe operation and limited diagnostics, (see page [12]). -
Page 4: Wiring / J1 Obdii
Connecting OBDII cable [J1] The CRC-1000 can only be used in US made engine/drive trains running SAE CAN bus, 2008 and newer. The OBDII harness connects direct to the OBDII diagnostic plug. The OBDII harness will need to be removed from the ALDL port, if engine diagnostics needs to be performed with a scan tool. - Page 5 Connecting Main Harness [J2] Wire colors Ground Output to activate “cruise” indicator on Dakota Digital dash or ground side of LED Orange Yellow Clutch Switch triggered by a positive voltage White Clutch Switch triggered by a ground signal Blue Constant power (hot side of brake pedal can work)

Page 10: Wiring / J4 Throttle Connections
Throttle Pedal Harness [J4] The throttle pedal harness is also a plug and play style, only for a GM pedal, and only for one style. The pins must be side by side; not front to back, nor a dual row of pins. The harness cannot be rewired for different pedals as they may operate on different voltages. - Page 11 A, C, D, and F can be ground or power, as our throttle harness merely acts as a pass through. When looking for a ground reference to ground the CRC-1000 to, one needs to verify the correct wire. 2008-2013 Silverados and Sierras – Color Pattern of 250-2766 throttle harness...
