Hi dbakez,
You need to use spare pins on the airbag socket to get the new supply into wheel and onto the heater control module as per circuit diagrams.
Some people run a new supply from the supply system in the footwell, but it was too difficult for me. I just use the supply from the cigar lighter in the centre armest. Is it an ignition on 12v supply.
So I added 2 new wires into the back of the SZL module then ran them behind the centre console trim and into the armrest cubby hole then attach a cigar lighter adaptor and plugged it in. bingo.
Do you know the pin numbers on the szl to use?
