2010 Toyota RAV4 Trailer Wiring Installation 

Glad it helped!

That sounds pretty advisable to me.

@@timkrouse345 This is not advisable. Many circuits wired in this way fail. For safety purposes, trailer lights require direct connection to a vehicle's battery.

Ignore the guy that says thats not safe, its basically a 12v supply from the battery just wires are ran for you already

Was the installation done at U-Haul? Here's a video that may help with being stuck in park. - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IDND0hl9Dbs.html
