How do I hook a 3 pin connector to a 4 pin?
First post here! I recently purchased a small camper and the runnig lihgts(I assume thats what it is) have a 3 pin connecter, can I just plug it into the 4 pin splitter I have or do I need an adaptor?...

Since the camper connector has "DC" embossed on the jacket, there is no reason to believe it has any pinout relationship with a standard 4-way trailer connector. I'd suggest to check continuity with the pins on the connector and frame ground, a running light fixture, any backup lights on the camper, any taillight fixtures, and a wire leading to the battery compartment (should have one of those three colors).
If you want connectivity to the truck, I'd suggest to buy a 4-way "Y" splitter (fairly typical and easy to source) and make a custom pigtail to connect to the camper. You can buy both genders of individual pins to make the pigtail (might even get lucky and find the 3 way connector to modify).
Good luck on your wiring, that's a sweet rig.
