Thanks for the replies. The two articles mfiver mentioned are the two I was referring to. After reading through them again, I think this is a doable thing. My installer guy is willing to try, anyway, as long as I can give him as many OEM parts as possible.

So that begs the question: Are brake controllers that different from each other? Why choose a Tekonsha Prodigy controller? I grant they're great for all-purpose trailer brake controlling, but isn't it a bit of overkill for occasional use of one trailer type? Is there an advantage of specifically using the Prodigy, instead of another Tekonsha model or a different brand altogether? It seems virtually every article I've read mentioned the Prodigy, but nobody ever says why they chose it. And why am I seeing that the controller should be mounted as horizontal as possible? Why would it matter?

Thanks,
Dave
