I bought a couple of the Project Farm recommended solar trickle chargers and just got it today. It has a few different connector types: direct to battery, cig lighter, and ODB port. Either the cig lighter isn't constant, or I forgot to hook it back up when doing the HU upgrades. It doesn't charge through that with the engine off. But it does through the ODB port. It even charges through that with the engine on. I've read that it's ok to do that, but have my doubts. I'll just unplug it before driving. I'd prefer it was direct connected to the battery, though. I need to see exactly how much cable I have to work with, and if I can run it through the firewall.
I plan to use the other one on my JK. Thinking of doing a semi-permanent install on the hood and direct connect it to the dual battery system.
