Attaching my 25 pin connector to a bluetti 200 max

Hello All I have a 2021 reflection 260RD 5th wheel. My question is; is it possible to connect my 5th wheels 7 pin connector to my bluetti 200 max so that I can turn on the running lights on the 5th wheel (rather than connecting to my truck)? If so, what kind of adaptor would I need. Thanks, john

I’m not sure what 25 pin connector you are referring to, but you can plug a fuse into your 7-pin connector to operate the running lights as in my post https://www.mygrandrv.com/forum/show...l=1#post149701

Thanks John. Sorry, I did mean 7 pin. Reverted back to my old computer days; 25 pin serial connectors. I'll try your solution.
