I just found some 98 Toyota Sienna leather seats to go int my 49 Chevy 3100. The drivers side is el ectric. I was wondering if anyone out there knows what the white wire and the blue wires polarity might be. There are only two wires connected to the seat. I'm not sure if one is 12v and one is ground or what. I thought maybe somebody may be able to help.

Thanks,
Bummer
