That ignition wire from the coil to the ballast resister looks like it's stretched to the limit. I'd make another one with a couple extra inches added to relieve the stress when the cab goes one way and the engine goes another.

Also, don't forget that the dizzy rotates counter-clockwise to advance timing and might pull on the two wires attached to it.
