Being I changed my steering wheel to a custom wheel, I lost my cruise control. I need to wire up new switches on the dashboard. I need to know which wire is the ignition, cruise on/off, set, resume and accelerate, whether in the column or under the dash. I bought 3 LED switches. One on/off and two momentary switches. I believe the ignition wire needs to be connected to all switches other the correct wire to control that action. Thank you.

You may have a bit of an issue with your planned set up. The reason I say that is the cruise is operated by varying the voltage on the Cruise Control Switch Signal in the BCM.

Basically the cruise is set by the "On" button on the wheel and it sends a 5 volt reference to the BCM to tell it to turn on. So this will work by using a simple toggle switch.

The "Set" "+" "-" buttons are all operated off of resistance. This means the BCM sees a varying voltage and depending on the voltage it knows what -speed to set the cruise control at. As you press the "+" or "-" it increases and decreases the resistance which changes the voltage that the BCM sees which tells it to increase or decrease the speed.

Does that make sense? Check out the diagrams (Below). Please let us know what happens. Let me know what questions you have. Thanks

It makes complete sense what you are saying. I did a lot of research on it, but I've seen videos of someone doing this to their Honda with just 3 switches and nothing else. I hardly ever use Cruise, but if I could restore it, that would be great.

Okay. Seeing as I have never done this, it may work with the momentary switches that you are using. Clearly I am not sure the actual logic the module is using. I am just looking at the wiring diagram and based on that making the determination that it is resistance based due to there being resistors inline.

If you have seen this work, then go for it and let me know what happens. Thanks for the update.

I was wondering if you could tell me which wire colors go to each function of the cruise control. I believe the plug that contains these wires lie underneath the clock spring. From what I was able to get off the internet, a gray, a dark blue and a gray with a black stripe are the correct colors, though I'm not to sure about that. I attached a pic of the wire cluster. If I knew which went to what, I can hook this up easily. I also need to know the 12v ignition wire color because it gets hooked up to each of the 3 buttons. Thank you so much for your help on this.

I think we can figure that out. However, can you get a little further away so I can see what it actually plugs into? From what I can tell the gray wire is the cancel/set/res buttons but I would like to try and get the connector view of this connector but I just need to know what it hooks to.

The connector is connected to the bottom center of the clock spring, but does not rotate with it.

If you do find the correct 3 wires, plus the ignition wire, here's my other mind boggling thing. The guy that did this on his Honda had an orange wire that provided the 12v constant power. He wired this to one terminal of the switches. The corresponding Cruise control wires were connected to the other terminals. All of these wires were on the column right near the ignition. He used 2 terminal switches. I will be using 5 pin Halo switches which need a positive and negative to light up the switch. I know what all the terminals on the switch are for, but need to know how to wire this. Take your time trying to figure all of this out. I want to get it right on my first attempt and really appreciate all of the help you are giving me.

How many total wires are on that connector? Is it just 6? I show three connectors on the clock spring. 2 of them have 10 connection terminals (not all filled) and the third has 4.

Sorry for not getting back sooner because I've been a bit busy. The pic I sent you was the terminal on the bottom of the clock spring that doesn't rotate with it. Then there are the 2 airbag connectors and the other is the female side of where I unplugged the steering wheel from. This connector does rotate with the wheel and is where I found the pins to connect my horn. I believe there is another connector behind the clock spring, but I didn't need to remove it because the new NRG Hub accommodates the clock spring when installed.

My mistake. The lower plug does have 6. The top plug that rotates has 7.

If I can throw in my 2 cents, I attached the connector diagrams for the clock spring.

Can you verify the connectors on the car side?

Your second diagram corresponds with the plug on the clock spring that rotates with it. This is where I found the positive and negative lead for the horn which is in pic number 1 from me. The other plug is bottom dead center of the clock spring which doesn't rotate with it. Pic number 2 from me. I am at work right now and can't provide you with other photos other than past ones from the last project you helped me with.

The other 4 pin connector in your pic might be behind the clock spring. There are other plugs behind it that need to be disconnected if I were to remove the clock spring, but my new hub accomadates the clock spring inside of it and I have it all wired nice and tucked away from the horn project.

Well, let us see if we can use those wires or the ones from the connector under the dash.

Hello Roy, hope I'm not being a pain. I thought you were going to get back to me with more info. Here's a diagram that I found online for the present GM Cruise Control. On top you'll see the Cruise Control Switch and the color wires that go to it. Also is the pic again of the lower connector to the clock spring that doesn't rotate with it. Are those the correct colors wires you are seeing in the diagram and can they be found in this connector. What's throwing me off, is can't tell the if one of them is blue because they seem faded. If I knew what each of those wires go to, I can figure this out. The other diagram you sent me, which is the connector that my horn is attached to, shows 1 gray wire for the cruise control, but I need 3. If you can be some help it'd be awesome.

The very first response form the other tech had the cruise diagram.

Do you have more than one connector at the clock spring from the body?

Yes, the one that rotates with the clock spring, the one in pic I just sent you, and a third that may have 4 pins in the back.

I attached the connectors in a previous post.

Did you see the cruise wires in the other connector?
