Dinghy towing w SMI AF1: Electrical Question

I was given an AF1 as part of purchase of 2013 Entegra and the coach part of install is complete (never removed). I am now looking to install what was removed from a 2012 Chevy Crew Cab C1500 truck into my new vehicle (2016 Denali HD).

As part of instructions for 2016 Sierra Denali HD after getting Transfer case/Transmission into Neutral I am to disconnect electrical from battery neutral. I have two* main concerns:
*1) For SMI AF1 as part of electrical connections I need to have
a)connection through firewall for breaking, and
b) break away connected to battery of Denali
- How is that possible/handled if I must disconnect battery?

*2) Will connections from coach/Entegra power the lights on the Denali?

Is there anything else I should be concerned about from an electrical point of view?

Good Morning,
If you must disconnect the battery I recommend the disconnect on the positive side.
This will allow you the get 12v from the battery (behind the disconnect) and still have a working ground for the breakaway circuit to use on the chassis.

If you choose to disconnect the negative side, you must run the ground for the Operating unit and the reed switch/Noti light back to the negative terminal of the battery.
Either way will work.

The coach will illuminate the brake lights on the Denali if you have run the tow wiring to those rear taillights and connected everything properly.

Let me know here, or on a PM if you have further questions on that AFO system.
Once in a while you get shown the light, In the strangest of places if you look at it right
