Monitor Battery, Solar & Truck Charging - Find Truck Wires in Fleet?

I have setup our Fleet to monitor the battery charge/discharge, solar charging, and now I want to monitor truck charging.

Where runs the cable from the truck for a front dinette Fleet 2016?

I would rather not take the camper off of the truck, which would presumably answer the question. The battery separator is under the driver's side dinette seat, so I'm thinking the wires must enter the camper near the separator. But that's a crowded area and before I cut tie strips, I'd like to know that's what I need to do.

The post on Automatic Charge Relay headed me down this path, as I have had at times lost truck charging due to connector problems. I already have a switch on the SurePower to manually close the relay (SurePower circuit diagram shows how to do this), and being able to monitor the charging would satisfy my curiosity about the charge rate, but more important, let me be sure charging works.

The setup is a Nasa Marine BM-1 compact battery monitor with a shunt in-line on the battery negative line:https://www.amazon.com/Clipper-battery-monitor-compact-white/dp/B0007916AW/ref=sr_1_8?ie=UTF8&qid=1501891623&sr=8-8&keywords=bm-1+battery+monitor (cheaper elsewhere).
and a Baylite voltage-current-power meter: with a shunt in-line on the negative line from the solar panel: https://www.amazon.com/gp/product/B013PKYILS/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

For truck charging, I will put a shunt inline on the negative side and the switch on my panel switches the Baylite to either the solar or truck charge circuits. The USB connector connects to a Morningstar MPPT charge controller so I can see what it is doing.

Our TriMetric monitors both battery bank voltages. One shunt does the amps monitoring. Seems to me if you can read truck battery voltage where it comes into the camper that you'd know if it is working or not. How much it is working seems like a job for one of your existing shunts.

This ^ I have my 2nd battery bank monitor wire hooked up to the post at the charge relay that comes from the truck battery.

That being said I haven't used it because the solar works well enough I've never run a cable for the truck charge!
