hope someone can help? just replaced my se leather seats for some msport ones now the se seats were heated but had manual adjustment levers the msport ones are electric heated and adjustment. looking at the big yellow plug I can see which connections are different and managed to wire a 12v battery to the extra connections in the plug to move the seats to a comfortable position to drive the car. now am I correct in presuming that I only need a + and - connected to the missing connecters in the yellow plug to power the up and down and side bolsters and rear backrest movements as once I connect the 12v battery to the connections in the plug all movements work. could I bridge the to wires to the heated seat connections to get a + and - feed if I can does anybody know which wires im looking for as don't fancy airbags and seat belt tensioners going off!
