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

No I know what torx are. I was just saying if a torque wrench using a torx head would do the trick.

I managed to get it though, the bit I was using was really crappy, so I ended up buying a new one and it worked.

[Edit]: Never mind, the wire that is connecting to the clockspring is the ground for the airbag and is replaced with the OEM wiring connection to/from the cruise stalk. Whew. Hopefully we get ours in the mail soon!

lolz funny about the airbag..i remember a video about an echo owner where the airbag deployed while hes drumming on his dash..knocked him out cold..

here i found it

[IllusionX]

the chances someone drumming on this steering wheel, the air bag deploying while someone is filming is VERY slim...

[Shroomster]

the tags for the video as well as the other videos recommended lead me to believe it's from a car insurance company....

Sorry for the delay in looking into this, but I was away on vacation. I looked this morning and agree that it should work with simply adding the switch.

Here is a quote from the 09 service manual:
"The microcomputer which controls the cruise control system is built into the ECM, and uses the throttle position sensor and motor as the actuator."

The stalk basically just has 4 switches and 3 resistors. The quick and dirty test (without removing the airbag) would be to short the ECM CCS pin to ground. If the cruise light illuminates on the combination meter, you are good to go.

25mph is the minimum limit for "set", but the manual doesn't list a speed limit for the on/off function.

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.

guys, those of you who are saying few minutes, be careful, some car systems can take over an hour to discharge the sustaining capacitors, also ground yourself to prevent static discharge.

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.

You said it.

Here's a comparison of SodiumDuck's 08 (left) and my 09 (right) (from when we installed our remote starters). Mine has the blue and brown, and his just has the black horn wire.



On the EWD, the spiral cable is just the block between 3B and 1A, as well as the block between 1C and 8A on the horn diagram on page 145. The spiral cable simply brings the signals off of the movable steering wheel. (If we had the European steering wheel controls, they would most likely connect through the last unused pin).

i'm beginning to get lost in all the technical talk. i should probably take a look at mine up in there.. unless someone can tell me if i have what it takes to do this by telling them that i have an '07 lb hatch?

[CTScott]

I was thinking that I was having deja-vu on this topic and found this topic from a while back:

Out of curiosity, have you checked to see if your combination meter has the two cruise lights.

[Sir A.Y. Atoyot]

No cruise light on my dash panel. It has a fog light icon, though (no actual fog lights in the car).

Canadian 2008 5-door hatch.

ah so since the cruise connects to the inside of the oem steerig wheel looks like i cant add it since i have an aftermarket wheel :(

You could install one of the aftermarket Rostra brand units, which doesn't attach to the steering wheel. Be prepared to pay lots, though.
