checking exterior lights
What is the "thing" that plugs into the six pin pigtail that activates all the exterior lights on the trailer? I would like to be able to check them before a trip without having to hook up the truc...

Flasher is not normally used for testing the lights. People use it to show off their rig or to locate it.
To test you must use a jumper and move it between different pins in the connector.
Understood.
However, sticking a jumper randomly into the 7pin connector any old way you can easily short the battery pos connection to the battery ground connection located on the same 7 pin plug. While it can be done it is much less ideal and a bit more tedious, not to mention highly confusing on which terminal you are about to wire.
Much better to buy a 7 pin socket and wire up with appropriate switches and a fuse on the battery charge line..
Like I mentioned, not all that expensive to wire your own tester box, makes for very quick testing, just plug in and play with switches. No need to check, recheck diagrams and hope you just didn't accidentally pin the ground to battery positive. I think you would be really hard pressed to spend more than $40 in materials to make a real nice testing box.
$7 for the 7 pin socket
$2 for fuse and holder
$3 for each toggle switch
$20 for a big enough plastic electrical box..
That one is 10"x6"x4"

$38 plus tax all in..
