Speartech  Plug and Play Cruise Control Wiring Gen V

The Speartech plug and play cruise control setup makes hooking up your cruise control quick and easy.

The throttle T-harness plugs in at the throttle pedal.  Unplug the engine harness from the pedal and install the T-harness onto the pedal, and then plug the engine harness to the other side of the T. Then plug the small connector on the other end into the cruise control module.  Note: After the T-harness is installed, the cruise module must be plugged in or there will be no throttle when you turn the key on.

Next, install your function switch.  This installs onto or in place of your turn signal stalk, or it can be remote mounted depending the style of switch chosen.  The other end of the function switch plugs into the cruise control module.

The purple wire coiled up is used for a cruise engagement light (not provided).  It is a negative (-) signal for an LED bulb.  This will turn on the bulb when cruise is active.  This is an optional hook-up and not required for the cruise system to function.

Finally, install the power harness by plugging one end into the connector on the engine harness labeled "cruise control" and the other end into the cruise control module.  The wires in the engine side connector are:

  5- Ignition (pink/black)

  6- Ground  (black)

  7- Battery (orange)

  8- N/C

  9- N/C

10- Brake Signal (light blue)

The light blue brake switch wire hooks to the same place as the brake light wire, so that the wire sees 12-volts when the brake switch is depressed. If LED tail lights are used a 5-terminal relay must be installed. See diagram below.

After hookup be sure to test the disengage features of the cruise control in a safe area.  If you have hooked something up incorrectly and the cruise doesn't disengage by brake pedal, you can always turn the cruise off from the function switch. We highly recommend all loose wires from cruise pigtail are tied into the Speartech wiring harness and not the chassis. If surging occurs when engaging the cruise then attach the GROUND signal from the cruise pigtail directly to the accelerator pedal's Purple Wire.

The Gen V cruise control kit requires you to plug into the OBD-2 port on the harness. You can hardwire to the CAN Hi and CAN Lo signals if you don't want to disconnect the cruise every time you need to plug into the OBD-2 port. Or you can use a splitter for the OBD-2 port.
