Hi all, I've advanced a little now, have bought the control switch from Niss 4X4, for $200 plus postage, they wouldn't come down on their price! Oh well will move on.
It has 4 wires coming out of the switch, plus a tab spliced on, witch I presume is for the horn, or earth? Not sure what vehicle it came out of, and looks like it has been modified already.

At first, after looking into the install job, it seemed a bit complex, so I contacted some professionals, mobile and retail radio installers, but they weren't keen to do the job!
So after thinking a bit more, and investigating my wagon (2002 4.8lt. Petrol model) it's looking straight forward, and may not be as complex as first thought, as long as the following work:
So my wagon has a cruise control system and switch installed from factory built and also a steering wheel air bag.
The air bag has its own yellow plug and 2 wires going through the clock spring. The cruise control has 2 wires and the horn, 1 wire going through a white plug, going through the clock spring, all on the air bag side of the clock spring.

As you can see, there are 2 spare terminal slots, in the white plug.
On the other side of the white plug, going into the clock spring, there are 5 wires going through the clock spring.

On the other side of the clock spring (under the steering column) there is 7 wires coming out. Therefore that must include the 2 spare wires. Good news. Remember there is only 5 wires used to date; 2 for the cruise control, 2 for the air bag, and 1 for the horn.
My head unit is a Pioneer AVH-Z5250BT and doesn't require an intetface module to make the steering wheel switch to work.

It has a single radio jack in the back of the head unit for the steering wheel control.

So I'm thinking: could I just join/soldier 2 pairs of the 4 wires together to make 2 double wire to plug into the 2 spare terminals in the white plugs, leading into the clock spring. Then pick them up on the outward side of the clock spring, find out where they run to/install new wires and plug them into the back of the head unit with a new jack plug?
Sounds simple, but is there something I'm missing?
Thanks in advance, cheers, Col.
