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

OK, sounds good. I'll look to check for the brown and blue wires, and ECM connector and pin 40. Are these all easily visible with the air bag off, or can you direct me to any threads with info on checking these.

No need to pull the airbag. Just remove the lower steering column cover to see the spiral cable connector (the one in the lower left is the connector you are looking for). It will either have just a black wire, or will have the black, brown and blue like this picture:




For the ECM connector, you have to pop the connector, and then you can look at the business end of the connector to see if the pin is populated (shining a flashlight into the connector will help you to see if the metal pin is in the hole for pin 40).

Thanks for your patience. Hope this is not sounding too dumb; how do I remove the lower steering column cover, and how do you tell which is pin # 40. Is it labeled?

This thread shows the location of the three screws for removing the lower steering column:

And, this one shows the details of checking pink 40 on the ECM connector. The pins are not labeled, but you can easily find the pin 40 position with the photo as a reference.

Got it. Doesn't look to hard. With gratitude, RH
