Found a Bosch Style relay attached to back of my WFCO power center. Any ideas?

[rgardjr]

Well it's winter and I have been going through my trailer to see what I can see. I pulled the WFCO 8735 power center out to look at the wiring and there was a Bosch style automotive relay screwed to the back of the power center. Any one have an idea of what the purpose of this might be? I've got an email into Jayco for the wiring diagram for my trailer. Man the wiring is sure a mess behind the power center.

Power steps, jacks, slide outs?

I do have a slide out. Seems like I would need a pair relays for the slide-one for in and one for out.

Slideouts work off the same source, the switch reverses the polarity.

Any optioned electronic devices? Macerator?

Disconnect it and see what quits working. I’d expect it’s for something big like a slide.

We have a winner. Curiosity got the best of me and I had to investigate. I unhooked the ground wire from the relay and tried the slide out, but it still worked. My trailer came with the Sani-Con macerator setup. I went out and flip the switch and ... nothing. So it ended up being for the positive side of the macerator pump.

I'll make a note of that should I ever pull my converter, also have that option.
