There's an EZ wire kit for the turn/stop/brake, that plugs into the existing wire harness. You'll need a circuit combiner to merge the separate turn/brake functions (wires) into the combined single circuit that trailers use, but that's pretty standard these days.
Yes, to run your inverter load, and to actually power the electric brakes if you go that way, you'll need a 10ga wire and associated inline circuit breaker (or fuse) from the 12v battery, front to back. Two, if you do electric brakes and want an inverter line. You'll also need at least one 10ga ground wire, too; not necessarily from the battery, but across your connector and to the trailer. Trying to ground through the ball/socket/receiver is never a good idea, esp. for any significant load.
Ok great. Now is the wire kit from ezwire.com? It seemed like the most logical place from a quick google. Where is the plug in the rav4 ev's existing harness? I am hoping somewhere easily accessible with out having to remove half the trims of the car. I'm going to call the places today to see if I won't need brakes. I hope it isn't needed as it would make everything easier and less expensive.
google says 10ga can only do up to 30 amps but you mentioned 50 amps is still ok and 60 on a short duration. Just how far are we pushing the wire here for 50 amps? I guess if I still need more power then I will have to add a battery outside the trailer to top it off/charge? That or run cables straight from the rav4's 12v battery, but I might need something thick like 0/2 gauge?
Ok, so I called the local sheriff then he sent me over to california highway patrol and the lady looked into it and she said that cargo trailers need brakes if they are 3,000 pounds gross or over. So, it looks like I won't need trailer brakes after all. The last aluminum trailer I looked at weighted onle 756 pounds, and I doubt it will get heavier than 1,000 pounds when I loaded so we should be good. That means I'll only need a kit for the lights. Might you have any suggestions asavage? Something more plug and play would be best instead of having to splice and dice cables
