TOYOTA YARIS 2014 CRUISE CONTROL INSTALLATION

We have installed steering wheel with cruise control & multimedia controls in our TOYOTA YARIS 2014. We got steering wheel from Al Sharjha used cars parts. What we need to do is ti just remove old steering wheel & installed new one with cruise contril & multimedia controls. First of all Disconnect battey's both terminals @ leave system for atleast 2 minutes. Never switch on car system with AirBag off from steering wheel.
