HiYes, it is possible. I did it today. So far, only temporarily, but the cruise control worked and responded. But everything has to be done. Buy a steering wheel with cruise control buttons, buy a cable reel, stretch wires. I did it provisionally today and it works.
I was trying to do the same on my crz when i fall on this post.
I put a steering with controls ( cruise and phone ) but nothing happen. I see on my android headunit that no signal come from the new buttons.
I think it s because i have to replace the cable reel, but i see that you say " stretch wires " could you please explain what i have to do with wyres ?
HiI wish I could help you but all USDM CR-Zs have cruise control built in. If that option did not come on yours there is probably a lot missing from the ecu to support it. Have you obtained the factory service manual for your market and trim? I really thought all CR-Z had cruise and Phone control apparently I am wrong. Of course a lot of it will not work if you remove the original radio and do not have the correct wiring harness for the radio stuff. The cruise control has no reason to be connected to the radio and in CR-Z there is an interface module between the factory radio and the Bluetooth for the phone functions but most replacement radios replace that and become the controller for blue tooth themselves through the radio and there are after market interfaces that connect to the steering wheel buttons you are probably missing all of that. Again cruise control has nothing to do with any of that.
You need to do more research and need some more understanding of what connects to what and how to make the aftermarket stuff work with what was in the car if it is even possible.
It's possible to finish. I did it. I have the original CRZ without cruise control, but now I have a functional cruise control. It is necessary to buy steering wheel buttons, cabble reel (with 20 pin without cruise control have only 10pin) , clutch switchI (I´em used a brake switch from a VW Passat) . Then it is necessary to stretch the new 3 wires from the gauge control module to the cabble reel. And 2 cables from the ECU to the brake and clutch switch. Then everything works View attachment 64207 View attachment 64208 View attachment 64209
Ok, if i undertand:But it is not easy. I had to get an old cable harness at a Honda service and use a small connector from it. I think it was a volume from CR-V 3rd generation. it is difficult to put new cables, and if you are not an electrician and you do not understand the diagram I put here, you will need help
