The controller also allows you to adjust for different trailer weights. A heavier trailer will require more braking force than a light trailer.
I don't disagree with this, but I wanted to add a bit for the sake of clarity.

You're describing the best brake controllers out there, but not all have the ability to vary brake force like this. The cheaper ones are known as "time delay" style controllers, and they have no way of knowing how much braking power the driver needs. You set them to a certain point, and they increase brake voltage up to that point over a short period once the brake lights come on. Whether you're lightly braking or in a complete panic stop, the trailer brakes behave the same. I *HATE* these kind of controllers, but they're out there.

A good brake controller, like the venerable Tekonsha Prodigy line, uses an inertia sensor to detect brake force, and varies the brake voltage to the trailer accordingly. They're far from perfect, but the best solution for a vehicle that doesn't have a controller integrated into the braking system.

Electric trailer bakes will not function without a brake controller. You'll be towing a trailer with no brakes at all, as there will be nothing to supply voltage to the brake signal line to actuate the magnetic actuators.

Sorry to have to open this again, but I am absolutely unable to find the plug for the brake controller adaptor anywhere in the area described on my 2017 Touring L I have been all through the area (at least as far as I can figure) and can't find hide nor hair of the plug to attach the 3045-P adaptor into. In the Pac1 pic (5th pic) attached, I circled a plug on the Pacifica that is the same type of plug on the adaptor, but I can't find the plug I need that Nails provided with the green wires coming out of it. The only similar green wires I see are coming out the bottom of the white box in the Pac3 (3rd pic) picture attached. After feeling through the loom on the different wire packs in the area, I am pretty confident the plug is not hiding inside one of those, but I've been wrong before. Can someone nudge me in the right area with these pics.

Did U try unplugging what you show in the last picture?I have a 2019 model and that looks like the dummy plug that I pulled to install the
3045P adapter.

Yeah...I have popped it out, but it is wired so if I were to plug the 3045-P into its spot, then it would be loose and no longer plugged in. Did yours have the red and black wire coming out of it like mine? From what folks have said, I should have a blank harness to plug into which led me to believe that and the white one to the right of it (also wired but same type of connector) were not what I needed.

I suppose I should also mention that mine doesn't have the factory wiring installed, but bought the OEM wiring harness. I took the van to a trailer shop and my mechanic as well, none of us were able to find the brake harness on the OEM harness or under the dash. I'm getting to the conclusion that maybe some of the earlier models don't have the harness on them.

If your van doesn't have the trailer tow package then you won't have the plug in for a brake controller under the dash!

Thank you. Weird that it is not stock on the van, nor on the OEM part for the specific trailer tow package. After searching fruitlessly the first time, I figured it must be on the OEM wire harness (82214522-AB) but when that arrived and didn't have the plug either, I was going crazy looking for it under the dash again. Gonna return the OEM parts and go with a hardwire solution instead. At least the heavy duty radiator was much more straight forward. Once I get that installed, I just have to take it in for the software update and I'll have the whole trailer package, just with aftermarket wiring and hitch receiver. Should still be up and towing by our first summer trip.

Thought yours had factory wiring,so it wouldn’t be any help .

the factory brake control plug

Here is a pic of under the dash of the plug for the factory brake control option.
