hi ,i have an 84 320i and i need a new temperature gauge sensor so i bought one online but the problem is the old one i took out was a single pin although there was a spare wire wrapped round it so i presume that someone replaced a 2 pin with a one pin at some stage. the new one has a 12 mm dia thread but the old one is a 14 mm dia thread so the new one is obviously too small to fit, i have been told that there is an adapter you can get to reduce the size to 12 mm but cannot find out any info on where to get one , can anyone please help otherwise my only other option is to get a complete new housing which i dont really want to do. thanks tony
