Sir your point is valid. But a combination of fog light like-switches would not look that bad. Plus a switch combo from kabli market if fitted perfectly in the slots would blend in. But yes, it would be a real pain for a driver frequently travelling on the motorway.
And about the dealerships services, If i am too convinced myself to pursue the idea (like zunny bhai was once- and Allah bless him for enlightening us all), I am gonna have to take it to a 3S, and ask them to open up the dash safely for once. Then i'll drive back home and take on the task from there.
I have a starter plan to check the functionality without messing in too deep. I am gonna ground the "CRUISE MAIN" input on the cluster and check if it lights on. The repair manual says, the cluster panel lights are only available in cruise models. And since they are already glowing, its all a matter of testing whether the 3 inputs from cruise buttons on the cluster are functional or not.
If that goes out well, then the question remains about adding the civic steering with an oriel clockspring or not. But even after that, you dont whether the wire harness on the downside of cable reel supports extra connections or not. Uptil now, only one wire is coming to the steering and that is horn relays negative end, to be shorted with column for horn operation. So its all a mystery before anyone opens up the dash.
EDIT: And about your concern if the wires mess up, dont worry, its a fail safe system. If the wires for Accel, Decel/Cancel short out, the only bad thing you are going to hear is your horn. As per circuit, you have drive these buttons from the the horn relay negative. As long as horn is not pressed, the downside of relay coil stays at 12V (Basic Electronics rule- trust me).
And if the CRUISE MAIN shorts out, well its already grounded to enable cruise function
Finally the live wire in all this scenario is the wire going into the ECU from brake switch. Its a normally closed contact. Means, if the wire breaks, shorts or switch contact has carbon, its disengaging the CC till correction. (A perfect example of a FAIL SAFE LOGIC)
