Bundle of unused red and white Wires on frame

[DW_DX3]

While under my DX3 32KD fixing a driver's side lean issue, as well as fixing wiring rubbing on the airbag valving levers (grumble grumble), I came across these wires on the driver-side frame rail, behind the rear axel and right behind the wetbay. Two pairs, and they do not carry voltage on them.

Any ideas what they are for, and more importantly, where the other end is? They go into the "main" Dynamax black harness, and appear to head to the front of the vehicle, but I do not see any obvious wiring in the electrical bay that would be for them.

Perhaps related to LP delete on my rig?

Depending on where the other end is, a pair would be very handy to power an auxiliary heater in the wetbay...

This time with picture!

You need to remember that they make one wire harness and only use the wires for your floor plan. If you start digging around, you will find lots of unused wires.

Just a WAG, but it probably uses the same wiring loom as the Europa, and that's the location of the Truma and the propane tank, neither of which is on your DX3.

Edit: Apparently Dr Quest and I were typing at the same time.

Thanks everyone. I am aware they make limited harness. My goal is to find the other end of them. If they are up in the electrical bay then that makes it really easy to add an auxiliary wetbay heater when the aquahot can't keep up keeping it warm.

Check the other side. I have bundled wires, unconnected, on both sides by the rear wheel arches. I have not checked for voltage but assumed they were additional lighting harnesses.

No other wires on the other side. I thought about lighting, but the wires are 12 or 10 gauge, which implies handling a lot more current than some additional lighting. I will put a wire tracer on them and track them down and share my findings. Just not looking forward to more time with my back on a cold concrete floor

To close on this, I traced these wires back to connecting with the Option switch on the dash, which is currently powering the large white lights on the rear of the rig. Turns out they are not Dynamax wiring but Freightliner due to wire IDs printed on them.
