Ok I can't figure this thing out and its not like there are a lot of wires to work with. The picture above is what I was sold and all I can find but not what I took out of my 65. What I took out of my 65 only had the 3 pin not the extra one on the outside of where the boot goes like this one. I was told just to plug the rubber boot with the wires back up, screw the accessory wires to the center terminal on the outside of the boot and it should work fine. I did that and nothing. Now I have it hanging below the dash so I can mess with it, does it need to be in the dash for grounding or anything I'm not thinking of?
