I wish I knew exactly what wire to use to install a brake controller in your 2007 Buick Rendezvous, but I can explain how to help you find it.

You are going to want to use a circuit tester like our part # 3808 and test all of the wires going into your brake pedal switch until you find one that sees 12 volts when the pedal is applied and none when the pedal is released.

I attached an FAQ on brake controller installations for you to check out also.

The brake controller we recommend the most is the Prodigy P2 Brake Controller part # 90885. This is the best selling controller on the market because of how easy it is to setup and use, and how well it works.
