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

No. It mounts under them, and the connector for the spiral cable is buried under there as well. Removing them is not a huge deal, it just requires some caution and care to not pop the airbag or break the clockspring.

Snapping the clockspring is a big concern. Very fragile piece. Airbag: not so much. Too many fail-safes built-in due to liability concerns.

I'd like to do this mod to my '08 HB with no CC wiring or dash symbol. I'll run a wire from the ECM A21 connector @ position #40 then to the aftermarket on/off cruise switch.

My question is this: I'd like to have an LED light to indicate when the "cruise control" is "on." Where can I find a hot wire for the LED?

The real cruise light is controlled by the combination meter, which gets the info about cruise mode over the CAN bus from the ECM, so there's no easy wire to connect the LED to.

I thought perhaps there was a vacant ECU connector position that was used by the CAN bus to send juice to the dash light when the cruise was activated.

nickhjort pulled apart his cruise-indicator-free combo meter and I had him check the outputs of the IC that drives the LEDs, before and after activating cruise. The hope was that we'd find an unused output that would be used to drive the cruise LED if present. Unfortunately, no such luck.
