Help identify plug on roof of lance 825

Agree, their schematics are very helpful. Reading the manual, it sounds like the cable "loops" in the galley and then terminates behind the battery. I'll keep searching in both areas and take pics when I find them.

Yes Solar pre wire plug on roof, inside would be a 12ga blue+ & white- wires terminating behind battery compartment. Pages 48 & 95 of your manual-

Theres a link on the TCU thread to Lance manuals. If you dont have a manual I would download and print a hard copy for your year. Worth there weight in paper. One of the things about Lance Ive apprecaited was the inclusion of schematics for the various camper systems, plumbing, electrical.

Just crawled up there this morning and confirmed that it is the SAE-2 connection. Next step is to use my wire tracer to send a signal down the line and see where it terminates.

That looks very similar to the SAE 2-way plug I had on my Wolf Creek 850.

Solar

It is a connection for solar. My 920 has it. There was a matching pigtail included when mine was new.

Sure looks like that SAE 2 type plug. I'll take a closer look tomorrow when it's light, but sounds like solar is the most likely candidate. It's definitely not the radio antenna as I located that inside.

I rooted around behind the control panels and I didn't see any obvious terminated wires. Planning to call Lance tomorrow and see if they can tell me where the pre wiring terminates....

In my arctic fox there is the same thing, which was pre-wired with solar from the factory. The plugin was an SAE 2 pin connector, bought one of these in 8gauge for about $4 SAE 2 Connector and just cut the end off i needed and plugged her in and attached 8gauge wire from it to the solar panel.

You will need to find out where the other end of that pre-installed connection goes as thats where you will need to put your solar controller and it should also have the pos/neg wire that also goes to your campers battery. In my arctic fox the location of the wires was in the wall next to all the other monitors/switches and was clearly labeled "pre-installed solar wiring location"

Good luck, have a look around for a pos/neg wire inside your battery compartment, and also maybe under your sink or some other area which a solar controller may be mounted. Or ask lance directly or maybe a lance owner will chime in.

Makes the installation extremely easy, my install took me about 1hr to install the panel and controller since all wire was already in place. All i had to do was screw panel to roof and cut out hole in wall to mount controller.

Can you trace those wires to where they lead? Maybe the battery compartment?

Are you sure it says "MT" and not "MC" connector?

Many solar panels use MC4 connectors, and a panel would have two connectors.

Do you have a radio antenna anywhere else on the roof? I'm just guessing. It looks like something was mounted there and it came off the mastic.
