Trailer wire harness question

Ok folks, I just installed a Fab Four rear bumper and I have a question. I need to extend the wire harness for my trailer lights. I already took the harness loose past the rear end and got just enough slack to plug it back in but the harness now has no slack at all and I do not like the way it is pressing on the rubber brake lines. This is not going to work for me. Does anyone know if there is an extension sold somewhere about a foot long to solve this? I can cut and solder more wire but I would rather have a plug and play option.

 

Amazon sells harnesses- be sure to check the color/connections though, you may need to cross colors if they are off.

Edit: wait- you just want to plug a female end to the male to extend it? Thats a recipe for a no trailer brake light fix-it ticket and even lack of working trailer brakes in the future when it fails- I know it’s a hassle, but I would hard wire extension wires into it and be done with it, you will be much happier and won’t have to worry about it when it rains or if they ever salt the roads on you.
