Which of the 3 aux leads is pos, which is neg, and what is the third? Does polarity matter?

Using the photo on the page Right is - Center is + Left is marked U. The case is marked and I made a 9V connector as it is marked and it works fine. YES! Polarity matters, I doubt they included reverse polarity protection. I looked and I did not receive any instruction sheet either.

Can you provide a link to the manual online? Why Does Amazon not have links to the manufacturer website for most things?

Sorry, no. Commonly the seller is NOT the manufacturer. I received a very small instruction sheet nothing such as a full blown user's manual. Sometimes the seller does post a link to the manufacturer's page for a user's manual. I agree with you, this should be a condition for selling on Amazon or any on-line seller site. Last, any question can be put to the seller on the product page, have you tried that?

What AWG are the leads on this device?

The wires are 12awg which means this device can handle 20 amps continuous current...maybe a little more intermittently...nowhere near 75 amps much less 150 amps. I would think the seller could be held liable for the item description. Please be careful and consult with someone familiar with electrical theory if you're not sure.

Can this be used Outdoors? Waterproof? Rainproof?

Dear customer, We do not recommend for outdoor use. It's not waterproof. Thanks.
