Electric Brake Installation Standards

I'm having some electric brake issues on my 2014 Forest River Wildcat 327CK FW. I know I can buy the RVIA standards for about $100, but I'm trying to avoid that at this time. Does anyone know if there's a site online where I can research or post and receive specific answers for a particular standard?

For example, I am experiencing random and uncontrolled braking. Whilst crawling under the unit, I noticed the electric brake wires are zip-tied to the springs. I'm fairly sure that's not an acceptable installation; in fact, I think it's prohibited to attach electric wires to part of the running gear, but it would help if I could point to a specific section of the installation standards/practices in my ongoing discussions with Forest River.*

I know uncontrolled braking signals could also be a TV issue, but I just had the truck checked out by Ford and they say the truck end is okay. This is just one of several poor manufacturing issues I've had with this unit. Anyone have a bright ideas? Thank you.*

You are right, brake wiring should never be attached to suspension parts. They should be attached to the axle, leaving just enough free wire run to the magnet wiring.
In a perfect trailer wiring diagram, all wires are the same length, one 10 ga wire(slight over-sizing) coming from trailer plug runs down center of trailer, then 12ga branch wires run to each magnet. None attached to anything that may chaff or pinch wiring.
In the real world the main wire is ran along one side of the trailer frame, that sides magnets are wired into the main, which then runs across (or inside) an axle to the other sides magnets. Bottom line, each magnet pulls 3A, wire sizing must be large enough to handle the total Ampere draw without creating high resistance.
I cannot point to the RVIA standard though.

RVIA standards won't help with that, but common sense will. Way too much extra wire (it appears) and as mentioned above--wire tie to axle with enough extra to account for axle movement. And, yes, all wires should be the same length, but that is never the way it is done.
Is this the way it came from the factory? If so, FR strikes again. If you have had some brake work done, then maybe someone else did it.
Why not locate a reputable mobile tech and have him look at it?
When you say 'random' do you mean when applying the brake, or at any random time?
