Rewiring Trailer Brakes - How to Allow for Axle Movement?

Check wiring for pitch spots/hung up spots

This is a given, do it with full extension. But if you run the shortest distance, from frame above the axle down to the brake, you have a chance of that wire catching anything as it is blowing in the wind. Follow the suspension, keep it tied tight except a little slack at the pivot points.
