Also, the Fords do not come with the trailer battery charge relay installed. It goes under the hood. It is supposed to be in a baggy with the owners manual, if you still have all that stuff.
Dang ... I knew I'd be found out. I do have the original baggy with a few odds and ends in it. However, I AM NOT an electrickity guy at all. This sounds like I need to run a separate line to the trailer for the breakaway unit battery source or are you talking about something else?
THe Ford with the factory trailer tow package have the trailer battery charge wire already. The relay goes in the power distribution box under the hood. Its probably the only socket without a relay. Owner's manual describes it too.
On the RAV4, you will need to run a battery charge wire (don't forget to fuse it!) along with the brake wires. Be sure to use a powered tail-light converter. Toyota cars in general need powered converters because the stock wiring is only sized for the stock lights, and not for the additional trailer light load.
