Frame rail wiring harness for a 2007 ford ranger 2.3l 4x2
 

I was replacing the cross member above the gas tank, when i was drilling out the rivet i went through the wiring harness that runs down the drivers frame rail. It looks like i just knicked the side but i did peel the insulation off a white, yellow and green wire i believe. I liquid electrical taped it up hoping it still works but would like to know what harness it is to look up diagrams incase i need to repair it.
Thanks!

I believe that goes to the factory trailer plug at the rear or the truck, there should also be a brown wire in that loom.
