I am converting a 68 charger from auto on the column to auto on the floor. I just got the short wiring harness for the console and the longer harness that I was told goes behind the drivers seat and then up to the kick panel. Does any one know what this is supposed to plug in to? My wiring diagram only says that it goes to the instrument panel. It is a 4 prong sort of connector along with a single connector and the ground. Thanks
