Polarity Reversing Pigtail

[Sewgratefulquilts]

I’m buying Renogy solar suitcase and have a Zamp solar plug on the side of the Motorhome. I know I need an MC4 to SAE adaptor. No problem finding that. But I also need a pigtail that reverses the polarity. I have read info on the subject until my head is spinning.

I am not capable of doing any wiring or any electrical work other than plugging stuff in. Anyone know where I can buy the pigtail and exactly what it’s called? A link would be heaven sent!

Thanks.

I would try to find someone to cut of the Zamp connectors and solder on MC4 connectors with proper polarity. Every connection (adapter) adds to resistance and reduced efficiency.
