installed tach, now no power

Posted a couple days ago about hooking up a tachometer. 70 Duster, rallye dash with the built in tach that was 1000 rpm off. When I was in there I removed a red wire that ran from the bottom pin on the rallye tach to the fuse box, plugged in at the spot where the red arrow is below as I don't want power going to the tach if I'm not going to use it. I have a service manual but it does not show wiring for the rallye tach. I now have no power to the car. My instinct is undo what I did last, which would be to replace the red wire, it's about 14gauge which I though was pretty beefy for a tach, but who knows who wired that in. I do have a red wire with a white stripe going to the spade listed battery feed. Before I start looking at all the other wiring, can someone tell me if that red wire could be my issue?
