03-07 silverado classic adding cruise

[Gagliano7]

I just added cruise to my 07 classic silverado. Mine didn't have the 4 pin plug. I went to a junk yard and picked up the 4 pin plug with wiring and pin connectors that plug into the block down towards the base of the steering column. Here is a video that shows you where to connect the four wires. 

 

Here is where you connect the pins in the connector. From multifunction switch which is your blinker and cruise control stalk.

Blue - B1 Cruise accel

Black- B10 Cruise set

Pink- B18 Power A lot of places tell you to use A2 for power but there is already a large gauge wire connected there.  

Gray-B32 Cruise control on switch

 

I also want let you know since i had bad multifunction switch how to test your cruise connector. Use a continuity tester and go from pink wire which is power to the wire you want to test. With B32 gray wire cruise control switch on test between pink and gray you will have continuity. Turn switch off it will be open. Pink to black B10 cruise set push button and you will have continuity and the same with pink to blue B1 push accel switch and you will have continuity. If any don't work you have a bad multifunction switch.

 

Here is a link to the wiring and pinout of the connector by the base of the steering column where the 4 wire connector is wired in case your truck like mine didn't have the connector.
