Question- Purpose for these wires.

[Jfaries]

I’m a novice. Could someone tell me what these wires are for? It’s a 2023 17MKE
Thanks

Those are for your electric axles. They're new on the 2023 models. (kidding, I couldn't resist)

Hard to see exactly from the angle of your picture but pretty sure those are the 12v power for your trailer brakes.

Probably for the ABS programmer. They starting to ship some of the rigs with an antilock brake system. Those wires are used during initial programming I believe.

As mentioned either for the electric brakes or ABS. If you could post another picture from the other side showing more of the wires we could narrow it down for you.

Yeah, what they said.

Vaguely in the picture it looks like 2 red wires and one set of white wires. The white wires should be the electric brakes and should come out of a hole on the axle up to the wire penetrating the lining. The red wires as mentioned are probably the ABS programming wires. If it's a single axle unit, then there are 2 ABS programming wires. For a dual axle unit, there should be 4. Are you seeing the same thing on both axles?

[Jfaries]

Yes I see the same set-up for both axles. I just wanted to make sure all was okay since they are not plugged into anything.
Thanks for all your assistance

Though I agree that’s what it looks like, I thought only Reflections and Solitudes were being equipped with those brakes.

Looking at the latest pictures those are brake wires. I am not sure if GD is only installing ABS on certain models, anything is possible. You are right that they were/only installed on those 2.

Thank You-Much Appreciated

Jfaries -- can you post a higher resolution version of those pictures? I have doubts, too, as to what those wires are based on Jkwilson and Country Campers posts.

[Jfaries]

Sorry these are the only pics I have right now. Expanding them does not seem to help much.

While color is not usually consistent blue is normally electric brakes. And I thought those were plugs not the splices I see them to be now, so I think that's your brake feed coming from the front splicing to the brakes themselves and the through axle wires.

[howson]

Jfaries -- definitely not the ABS test connections. As Neil stated (and others suspected) they are splices. From the limited perspective of my experience, they brake wires aren't normally zip-tied to the axle like shown in your pictures.

OPINION: Given the harsh environment under there while on the road consider a better arrangement to ensure they aren't damaged inadvertently.

After sending pictures to Grand Design and getting a request for additional pictures. This is their response:

These 2 red wires are magnets for your brakes and the black wire in your photo should be connected to this loop as well. Thank you for sending the additional photos. I have confirmed that these wires are properly connected.
