Do you have any photos of the plugs and which colour wires go where?
I'm about to do the same, putting '14 power seats in my '02. The wires on the base of the '14 seats are simple enough but the power wires from my '02 are MIA. At one point the converter bundled up a mess of unused plugs and stuffed them in the B-pillar. I'm just trying to figure out which plug out of the 6 or so various shapes belong to the power seats.
FWIW....I just put a 2011 power driver's seat in a 2008.....and the plugs were different....the good news is it's just 12V and ground.
Does anyone know what kind of power the power seats actually pull? I have an unused power point that I found buried in my bundle. All I'd have to do is splice in the proper plug. However, it is only a 20amp circuit and it appears that the power seats are normally on a 30amp circuit.
