Corsa D Heated steering wheel

[Aaron721]

My heater is really bad on my car, I have read a lot about Corsa D have bad heaters. It takes about 10 minutes of driving before it even gets warm. I am fine with putting a jumper on for driving it’s just my hand are always cold. I know as an extra you can have a heated steering wheel fitted when buying new. What would I have to do to fit one myself, looked online, seems like I need a heated wheel (obviously) then a new wheel squib to plug the wheel into, then what would be after that would it be wiring from the squib to a simple on/off button? Is it probably best to pay someone who knows what they are doing to do it?
