Thanks NinjaTurtle2.5, would have been a tad expensive for me to call them from this end as im in Queenstown New Zealand. They have been great through email conversations though. Thanks for the advice though!
Well I just managed to make it all work! I pulled the trim for the dash off that's around the steering wheel and straight away found the OW & VW wires. Tested them with a multimeter and got nothing (scratches head). Then realised that the LAN module would still be connected, so pulled the socket apart and put the multimeter on the correct pins and straight away got the resistance values I was looking for when i pressed the buttons on the wheel.
So I snipped the wires and taped up the ones on the LAN side. Wired the VW wire to earth, and connected up the OW wire to the ASWC. Plugged it in, powered it up and the ASWC did its programing thing in a blink, and off we went. Works a treat!
Have to say im very impressed with the AXXESS ASWC. Works a treat and if it wern't for the LAN module been in line, it would have been a breeze to install. It sure was a breeze to get up and running once I knew the wires to patch into.
I'm going to send a comprehensive email to AXXESS so that they can pass this data onto other people that may wish to install one of these. I don't want others going through the same heartache as I did!
Thanks once again SVXdc for pointing me in the right direction. This forum is great !
