How to Know If Vehicle Wiring Will Be Overloaded By Connected Trailer Lights
Question:
You recommend part C55774 Curt T connector when using 7pin and 4 pin at the same time. My current setup doesnt allow both doors to be open at the same time. I would like to know how you can test to be sure you would not be overloading the sytem and causing a fire hazard or continuous fuse blown. Thanks

If you were using Curt T-Connector # C55774 and wanted to make connections at both the 4-pole and 7-way at the same time you could add the current draw of the two connected trailers/devices (like a tailgate light strip) to know whether this would exceed the rating of the circuits.
The online manual for your 2015 F-250 indicates multiple separate fused circuits for the various trailer light functions.
Fuse 10: 40-Amp for Trailer Tow
Fuse 22: 30-Amp for Trailer Brake Controller
Fuse 26: 30-Amp for Trailer Tow park lamps
Fuse 70: 10-Amp for Trailer Tow backup lights
You'll need to determine the current draw from the items connected to each separate circuit in order to know if all of the connected trailer lights on that specific circuit will overload its fuse rating. If you cannot find current draw in the items' specs you can use a meter to measure.
