Flush Mount Female 7-Way Trailer Connection

Question:

Hello - Im going to install a female 7-way Harness and ONLY use the 12V and Ground to a Lithium battery installed in my trailer. The Lithium battery will be used to run the lights in my cargo trailer CANNOT be directly connected directly to the tow vehicle alternator. So my play is to install a 7-way female plug on the front wall of the cargo trailer into the strong aluminum pebble guard and wire it directly to the lithium battery INSIDE the trailer. When I stop, Ill simply pull the 7-way male from the tow vehicle harness and plug it into the NEWLY INSTALLED 7-way female harness on the front of the cargo trailer allowing me to run my interior lights and 12v low amp refrigerator. Because the 7-way male MUST be unplugged from the tow vehicle, Ill make sure I never accidentally connect my Lithium battery to the tow vehicle alternator. What I need though is a very reliable, flush mountinch 7-way female receptacle. This mount here would be great if it were flush mount. Price is right too. What do you recommend?

I recommend the Pollak Metal 7-Pole # PK12703 as being the most flush mounted 7-blade available. This will push more the plug inside the camper which will cause the interior to require more space than the others.

The Pollak Heavy-Duty, 7-Pole # PK11720 that you referenced uses the less common 7-pin connection and will most likely not work for your application.
