> Splice them into your trailer wiring
That's what I did. I went up about 4" from the 7-pin plug, cut the necessary wires, used uninsulated butt connectors with a closed-barrel crimper and adhesive-lined heat shrink to splice in a 6-pin Deutsch DT connector pigtail, then built my own wiring harness that plugs into the Deutsch connector and ran it up to the headache rack.
Went with the 6-pin Deutsch connector since I only needed 5 of the 7 wires (LT, RT, Tail, Backup, and Ground) and 5-pin Deutsch connectors aren't available. Deutsch DT connectors are frequently used in the automotive aftermarket (probably more so than Delphi Weatherpack connectors). I know Rigid Industries uses them for their LED lights, and Smith Race Wire uses them for parts of their custom wiring harnesses.
Also, since you can only close-barrel crimp one end of the uninsulated butt connectors, I chose to close-barrel crimp the side that had only one wire (since closed-barrel crimping is more secure, and the one wire was looser in the connector) and used Channel Lock 909 Pliers to crimp the end with two wires.
Once you made your harness, make sure you slip it into some split wiring loom. Using a loom insertion tool makes quick work of that. Wrap the wiring loom with non-adhesive dry vinyl tape for a factory-finished look and to avoid a gooey, sticky mess in case you need to unwrap the wiring harness in the future.
Finally, a good wire stripper will save your hands a lot of fatigue compared to using a standard wire stripper that you have to always pull the wire through.
