I'm building a camper top for the H3T and need to extend the full 7 pin connection into the interior of the bed and still have the factory 7 pin available for towing. A friend used one of these to add a 7 pin connection on his F-250 for pulling a gooseneck, and assures me that "99.95% of 7 pin bumper connectors are the same". I took a quick look under the bumper today but it's a tight fit in there and I'll need to disassemble my factory 7 pin to determine if it indeed is modular and will accept this extension. Compounding the issue is the fact that I have a 315 spare hanging underneath which also cuts down on the available space near the factory 7 pin. So does anyone know for sure if the factory 7 pin can have this extension added to it? And if anyone has added one, where in the bed did you mount it?

Thanks, Jeff

 

Not sure why you need the full 7 pin extended for a camper.
I can see the need for AUX 12V and Ground but not the rest.

I have this on my H3T for AUX & Extra Reverse lighting it fits inline between the factory connections just fine due to the "7' extension with right-angle plugs for easy installation".
CURT 7' CUSTOM WIRING EXTENSION HARNESS (ADDS 7-WAY RV BLADE TO TRUCK BED, PACKAGED) #56070
Personally, I wouldn't buy that foreign Krap when it has to do with electrical/wiring.
Buying CURT guarantees fit on all plugs, proper wire gauge, proper wire insulation and built to USCAR specifications.

• Routes a 7-way RV blade socket into truck bed while retaining use of rear socket
• Simple plug-and-play design eliminates the need for cutting or splicing
• Allows for easy connection of 5th wheel or gooseneck wiring
• 7-way connects tail, brake, reverse, turn signals, brakes and auxiliary power
• 7' extension with right-angle plug for easy installation
• Spring-loaded dust cover keeps connector clean when not in use
• Slit loom keeps wires contained and well protected

 

Since the camper will cover/hide the 3rd brake light on the cab, the plan is to place an aftermarket LED strip across the back with running lights, L/R blinkers & brakes, and reverse so there's those 4. Add ground and there's 5. Add some floods and there's 12v power, makes 6. So the only one I won't really use is trailer brakes.

Where in the bed did/would you mount the receptacle?

Thanks

 

Mine is mounted under the bed.
I wouldn't permanently mount it in the bed.
I would run the 7 pin pigtail to the bed connect your 7 pin harness for the trailer/mods you are doing and heat shrink the entire connection and secure with zip ties.

 

OK Thanks for the info.
