T@B 320 Trailer Ground

sranderle · August 2019

Where is the overall trailer ground located at? I've never noticed a ground in the battery area.

Thanks

On my 2017 Outback, there is a junction box of some sort under the trailer, directly behind the propane box. All the battery wiring appears to disappear into it. Under the driver's side bench, there is some sort of wiring block. I searched around and didn't really find what exactly these are (or I didn't search the proper term) so I'd like to know what these are, too.

I agree with @pthomas745 that the Trailer Cabin Systems Ground Busbar is located on the floor of the Power Center compartment. My 2018 320S matches his 2017 Outback.

Some pictures follow.

Ground Busbar

Note: My unit has a Black Wire from Junction Box to Busbar for Battery Neg -12VDC. This is not factory standard as I had to replace the wire due to an event caused my me.

Thanks @MuttonChops . Bussbar was the word I couldn't remember.

Howdy, Stranger!
