Center High Mount Stop Light (CHMSL) Location on a 2006 Chevy Silverado for a Third Brake Light

Question:

I read a QandA on wiring a third break lamp in a 2005 Chev. Silverado #26158. Does the 2006 Chev. Silverado 2500HD have the same wire. How would I connect a 2 wire break light to this system. The break light system in question is on a Western Sand Spreader.

The 2006 Chevy Silverado will have the same wiring situation as a 2005. Locate the wire loom under the truck and above the spare tire. Like the question and answer you have referenced states, if you cut back the loom often times there will be 2 additional wires. The Light Blue wire provides a lead for a camper shell brake light. The other, a Light Green wire, is for the reverse lights.

To make sure you have found the correct wires, use a circuit tester like # 3808 to test the wires.
