No-cut trailer wiring?

[davepl]

My truck had the trailer wiring option, but it was installed really badly. They literally blew a 1.5" hole through the frame with a cutting torch to run it. I fixed all of that of course.

Anyway, I'm wondering if there is a harness that will allow me to add trailer wiring, including an electronic brake controller, without cutting any wires. I could likely invent and fab one with the right Packard connectors, but I'd be happier buying a pre-made one since I'm not a trailer guru.

Anyone know if there's something like this available for our trucks? I prefer M&H if possible, but will take what I can get on this one.
