Will Installing a Trailer Wiring Harness Cause a 2010 Toyota RAV4 to Not be Able to Start
Question:
I hooked up my 2010 RAV4 as shown on the video. I started the car and it immediately cut off. I undid the installation, turned the car on and it immediately cut off. I started it again and it was fine. Something tells me if I would have tried starting the car again after the installation it would have been okay? Let me know your thoughts before I go through the trouble of re-installation. Thanks.

Sometimes, if you leave the doors of the vehicle open long enough while installing the harness it can drain the battery. It has happened here to our installers before. It could be something that simple.
If you had the negative battery cable disconnected prior to installation then it may have caused a sort of reset for the computer on your 2010 Toyota RAV4 and that could have been why it behaved the way it did.
There is nothing in wiring harness # 118412 that would cause the vehicle not to start. The harness plugs in line with the vehicle tail light wiring and gets power for the trailer lights from the vehicle battery.
It is also possible that something got nudged or maybe came loose by accident that caused this issue. Everything should be perfectly fine if you go ahead with the installation. This is the first time I have heard of any issues with a RAV4. Make sure the last step you do is inserting the fuse along that power wire.
