If you have an iPhone I could FT with you and show you where everything is at. I’d just need to get the wife to leave her Expy at home tomorrow. PM me tonight if needed.

Thanks! Your pictures in this thread helps me a lot. I think that’ll be sufficient.

It’s all installed, but to get it working with 12v yesterday I had to run off the battery with a relay. I couldn’t get anything when probing the large orange wire under the hood. I must be missing the fuse in the fuse block.

adamsdaddy, did you have to add a fuse or do you know what number it is in the block? I saw things listed like “Trailer Module”, which has fuses in all of them, but I couldn’t find anything in the owners manual that was specific for the trailer 12v.

Anyone have a source for the $40 OE brake controller mentioned above? All I see are $80-$100. If that’s the price, I’m ok with it. But if there is a less expensive source, I’d jump on it. The Tekonsha P3 I have is nice but I still haven’t mounted it. No need to put holes in the dash if I don’t need to, right? Everything is operational, just considering the OE setup.

I think you may be referring to my post earlier.
It wasn’t written very well the $40 more I was referring to was total cost of the project and not a $40 controller, sorry.
Cheapest I have seen was $76 on eBay all the other main part suppliers are $80-$100.
Sorry for the confusing post earlier

Gotcha. Makes sense. I was starting to feel a little crazier than normal! Ha ha!

Responding to post # 42. I saw a you tube video that said the computer doesn't sent power to the 12V orange wire unless it recognizes a trailer is hooked up. The guy hooked up a couple lamps to the 7 pin connector and he got 12v.
