I have a '66 mustang and a set of '02 mustang seats which are installed. I can't for the life of me figure out how to wire up the driver's seat up. I contacted the Ford dealer where I bought them from and they said to use an Ohm meter on the 4 wire pigtail under the seat. Ohm meters measure resistance when powered not when they are not. Can anyone unplug their pigtail and see which is +/- for me. I would appreciate it.
