Review: Tres facile à installer par contre le positifs qu'il recommande à brancher sur la batterie moi je l'ai branché sur la prise 12 volts dans le coffre j'ai donc sauvé beaucoup de temps et fonctionne très bien
Review: This is the right one to get!!!! For the record I don't know anything about cars. U-haul sold me a universal kit and I was completely confused. Their video was sounding like it's a quick snap and click job. Universal kit does not work. It did took myself and a friend's help 3.5hrs Like I said I don't know anything about cars. Jacking up car works but the bottom of car is really close to my face... If you know someone or somewhere have a car lift, it will make it easier. We switched to a ramp to pass wire up to the battery. Everything is straight forward I used video on YouTube for the most part. Not everything is shown but 90% is all there. The kit have everything you will need. Crimping wires on butt connectors is not easy on two different gauges of wire. I thought you not supposed to have smaller size wire for big butt connectors. One end fits nice and tie, the other is smaller gauge wires??? These are not heat shrink butt connectors so no solder or anything. Would be nice to have a spare just in case mess up. (Especially beginners like me.). Spare fuses was provided. Paper Instructions was helpful, but font was small. It's hard to read... In conclusion, this kit works great for 2023 Toyota RAV4 TRD. I would recommend to anyone I know. And tell them don't get universal kit...

Easy, quick install. Works great. MAKE Sure to sand off the paint on the car body where the ground connection will attach and tighten snug. Not over tighten but snug.
