Confused about SAE connector pos/neg wires...

Why not something like this....

I use these on the trolling motor to battery setup. In between I have the same connectors on the PWM unit so all 3 pieces are quick connects. The beauty of the setup is that should the PWM fail-and they sometimes do-I can just take it out of the system and use the trolling motor the old way. Nice connectors, not waterproof.

I thought about using those as I've heard they are tougher. But NOCO doesn't make an adapter for those for its chargers and I'm hoping to make it one integrated setup. So I'll probably just go with the SAE for now.

I hear ya. It’s tough to clip off a perfectly good connector! My Dometic truck beer fridge came with a POS hard plastic cigarette lighter type plug on it. I kept trying to keep it together because it would fall apart all the time. I was about to order a whole new cord when I thought about Anderson plugs. I swapped out the outlet I’d installed in my bed for a dual Anderson outlet and cut the plug off my fridge cord. Have had exactly zero issues since…

That's what I have done with my SAE plugs also. It actually came into play on the last trip to Henry's Lake. The weak point in all my wiring was right at the PWM connections. One of my crimp on connectors came loose after a year and half of shuttling it around. I have since rectified the problem and it should be good to go for a long time.

So, I'm looking to add some quick connectors to my trolling motors (2 Minn Kotas, 30lb and 50lb), LiTime 50ah lifepo4 battery, and NOCO Genius 10 charger. SAE connectors seemed to be the best option as NOCO makes a nice little SAE adapter for their proprietary charger quick connect.

However, I don't understand how you do the positive and negative terminals and keep things straight. Take this set of two SAE adapters:

Amazon product ASIN B08Z86MCV5
They both have the positive wire on the male side and the negative on the female. But that means when you plug them in together, then you're switching them around. So if you installed one normally on the battery, you'd have to install the one on the trolling motor backwards (red SAE to black trolling motor wire, etc)? The photo in that product listing even shows them being backwards:

This makes no sense at all to me. Are there other "male plug has negative wire" SAE adapters out there? Or does everyone just have non matching wires around?

If you are installing YakPower for lights Yak considers the 'red' terminal always from the battery directly. SAE will have the 'red' wire on the 'female' SAE connector. You cannot kept polarity correct if you do not pay attention to what you connect. Look at this link it has a mulipack of the needed 'battery' connect to splice. https://www.amazon.com/gp/product/B0CMTXQRLS/
 
Hey Josh, next time you are trying to figure out what cables you bought and then left unlabeled in the bottom of the "boat projects" storage bin, it's these 24" 8awg SAE connectors:
