Hi guys, can anyone help me please. I am trying to retro fit power heated seats from a 2002 IS300. I have everything working except the heated seats. From the white connector block I have a thick white cable (ground) a thick white and black cable ( live ) a very thin pink / green cable ( seatbelt warning i think) and a thin red and blue cable ( which I dont know what it does) What wires get the heated seats working? please please.
