2005 Chevy 2500 – Adding Cruise Control With Manual Transmission

Bryan C: My truck is a 2005 Chevy Silverado 2500HD WT 8.1L 6 speed manual crew cab short box….Just read about a kit for adding cruise control, very interesting….will it work with the manual transmission? I don’t know if when shifting the clutch disengages the cruise like the brake does? I’ve had older Chevy trucks with manual and cruise combo but can’t remember how it worked….any insight will be appreciated…. thanks in advance

Sparky: I have never been asked this question before but according to the wiring diagrams it should work with no problems. The clutch switch should already be installed in your truck. This is indicated by not being able to start the engine unless the clutch pedal is depressed. The clutch switch sends a signal to the PCM just as the stoplights switch does. Either signal will make the PCM disengage the cruise control.
