Here's what I did, thanks to Dragon.

I hooked up to #4 terminal and grounded to the ground stud on the frame.

Then ran the cord through the front grill and protected the paint with a microfiber cuz the car will be covered after I clean it up this week.

I use a Schumacher 1.5 Amp Speed Charger which is also a controlled trickle charger. It's idiot proof too, it will not charge if you're hooked up backwards. I bought it 9 years ago when I first stored my 2011 Camaro 2SS. It was $29 at Wal-Mart.
