I plan to install a battery tender in my 5BW. The negative terminal is easily accessible; the positive terminal is under a cover that can't be removed unless the trunk liner is removed. Before I start removing push-pins and yanking on things, I figured I'd ask if there was a how-to for removing the trunk liner? I have come up empty handed Googling.
 
FYI, there are terminals under the hood should you choose to go that route.

The last time I parked my 5BW for a month, I used alligator clips on the two big leads under the hood, so I get that it can be done that way. But I prefer having a permanently-installed little dongle that I can easily plug a battery tender into. And I'd rather have pigtail coming out from the trunk rather from under the hood.

On my ZLE, I permanently installed it under the hood with an extension run so that I can access it through one of the openings in the front and never have to open up the hood.
 
There are four pushpins along the edge of the panel at the left side of the trunk. The pushpins are an absolute bear to get out, as far as pushpins go--I used a standard pry tool but all it did was bend the little metal tabs that the pushpins went into. I dug out my plier-style pushpin removal tool and that did the trick. https://www.amazon.com/Fastener-Automotive-Upholstery-Dashboard-Fasteners/dp/B0CBYLBYXM/

After removing the pushpins, I just peeled the cover out of the way enough to get access to the side of the battery with the cover over the positive terminals. Then it was just attaching the two eyelets to positive and negative terminals on the battery, and putting everything back in place.

This. I did the a similar thing on my Shelby. Attach the plug and play extension that should come w the tender to the battery under the hood. It has ring terminals and about 6” of working. When I didn’t plan to drive the car for more than a week I would pop the hood, plug in the extension and rest the hood on the stops.

Don’t make it harder than it should be.

I plan on hooking up a battery tender for the next few months while old man winter is in town.
I would like to hook the tender pig tails directly to the battery, but incase that does not happen, where are the terminals under the hood located?

Left side of the engine bay.

Purchase a Pulsetech XC-400 and the battery leads and install like LF4472. The charger is on sale and no battery tender or other product can replicate the PulseTech frequencies. According to the the lead engineer, PulseTech will completely dissolve the gunk on the plates while the other brands just hit it with pulses, and it falls to the bottom of the battery case. Theres a reason that every branch of the service use the products. As the story goes, a series of about 10 batteries failed on Humvees. The military wasn't happy and once received PulseTech determined that each of the Optimas was between 11 and 13 years old. You can't ask for much more of a torture test. And yes, this military branch was astonished. Its on sale for $69.99 and if you have a bunch of toys, you can get the QuadLink device that allows you to service 4-batteries at a time.

My original dual channel Pulsetech is still working after 14 yesrs but I needed a spare for a car stored elsewhere.
