thanks freddie, I think I will definitely relocate the box to the inside of the car, perhaps rubber o-rings can reduce vibration and keep a layer of air between the box and the firewall. The points vibrating loose i think was just a matter of them not being installed tight enough. The white wire is for the magnetic pick up, it's either the white, or the 2 wires (purple and green). On mine the designated wire for the tach is blue and it goes directly into the side of the box, it did work the way it was installed, rev limit and all. The white is simply taped up. Just concerned about the time delays and unable to pin point the problem.
