Hi everyone, I need some help. Internet research has come up inconclusive. How do I know if my '04 Sequoia will charge the battery on my teardrop trailer? I have the seven pin connector and I'm getting ready to install electrical on my trailer, but I'm trying to figure out how to set up the electrical. I think I have the solar figured out based on other forums, but is there something specific I need to do to have the trailer battery charge of the Sequoia's alternator? It seems possible, but again, internet research has proved inconclusive. I'd like to know this before starting to buy the parts for the trailer. I recently bought this new trailer from Escapade Campers, and they don't do electrical. They installed all the wiring, but I need to set up the battery on my own. Thanks!
