2004 Grand Prix gtp - So my heated seats are on the fritz and I believe it's the climate control switch panel that has the heated seat button on it. So I went to the junkyard and got one but it's dual climate control where mine was not. I would like to upgrade it to the dual if possible but I only have one 24 pin plug where the dual deck has 2 slightly smaller connections. Is there a work around with some sort.. maybe a harness conversion...
