DIY - 2009 Cruise Control for $10, without pulling the steering wheel and airbag

So I just wired the black wire from the d3 connector in with the red and blue wires. The horn when pushed turns on cc but the switch still doesn't do anything. Am I missing a ground or a power wire for this?

Post a picture of how you wired your switches and your connections to D3. It does sound like you have an issue, as the horn pad grounds to black wire to make the horn honk.
