Did you happen to get the part Number or any name on that breaker? I can't really make it out on the picture.
My harness matches up well to the 69 Camaro's I saw on that website but that breaker doesn't look anything like the one for that car. I would probably also need the harness that I showed in the link.
So I am guessing that I just plug my power wire into that adjacent slot by the breaker and I should be good to go. I assume I need the relay though.
The previous owner couldn't get the top down and ended up cutting the lines and draining the fluid and put it up/down manually. I wish he would have checked on the electrical side of things first.
