I am in the process of following in @Jean Mercier's footsteps to connect the solar panel on my tent through the rear right external roof power outlet (as described by Jean here). As shown in Jean's helpful pic as well as the Buzz Overland pic of the same area in their Gutted Grenadier thread, the internal connector for the roof power outlet in their builds was a DTP connector - just like the connector at the external power outlet:

Imagine my surprise when I finally removed enough trim panels to take a peek under the headliner and found that unlike the internal DTP connectors shown in the pics above, my internal right rear roof power outlet connector is something completely different - here they are disconnected:
I've done some online research trying to find out more about these types of connectors and have identified them as Yazaki Part Number 7282-6445-40 (my first pic above - male housing) and Yazaki Part Number 7283-6445-40 (second pic above - female housing). These parts can be found on Aliexpress and Amazon as "7282-6445-40 7283-6445-40 Automotive Electric Tail Door Wiring Socket" or by just searching the individual product numbers. I ordered this Male/Female Set from Aliexpress.
The failure to find DTP connectors as expected is a little concerning, since the Yazaki data info (7283-6445-40 and 7282-6445-40) for these connectors rate their "Allowable Current" at 20A.. We've likely all seen this diagram showing the amp ratings of the roof outlets:
I understand that in the standard setup the driver's side front outlet is rated at 25A for a light bar and the total for the remaining outlets is 25A, which is understandable since those outlets are all daisy chained together - as shown in this Buzz Overland pic:
But if the internal connectors (like the ones shown in my pics above) are rated at 20A (unlike the DTP connectors rated at 25A), does this pose a possible problem if we hook 25A worth of gear to our three rear and passenger side power outlets?
