Can we do this? (aka The DIY Cruise Control Thread)

[Sir A.Y. Atoyot]

I just checked - my car ('08 5-door) doesn't have the wiring from the spiral cable to the ECM - nothing coming from that plug except the thin black horn wire. If the wiring for cruise were present, there would be two more wires.

So, installing cruise is probably still possible, but unfortunately it's not just a matter of adding a switch.

My '09 has a blue wire in pin 1 and a brown in pin 3.

When I look at the models that the stalk part number is applicable to I see 06-09 sedans, but only 09 liftbacks.

wire 1 and 3 from the stalk is connected to 3 and 4 on the spiral cable

The stalk connects to the spiral cable on the steering wheel hub end, but the connector he pictured is the output of the spiral cable, heading towards the ECM. In his picture, the CCS wire (blue on my 09) is missing.

I've done some research with the documentation that members have provided, and I can assure you that you need two wires coming out of that plug, in addition to the horn wire. One of them is blue and goes to the ECU. The other is a yellow ground wire.
