Curt Custom Fit Vehicle Wiring - Sienna Trailer Wiring Harness - C64WR Review

Hi there. I'm Michael with Today, we're going to take a quick look at this Curt T-Connector Vehicle Wiring Harness. This harness is going to be a very simple way of adding a four-pole flat trailer connector at the back of your vehicle, so that you can hook up to your trailer and have your vehicle's lights be sent back so that your trailer is going to be displaying the same brake lights, turn signals and that sort of thing. So any motorists coming up behind you is going to know exactly what's going on. Now, this system is a custom fit for your 2021 and newer Toyota Sienna.

It is designed specifically to be very easy to get installed rather than having to cut any of your vehicles light wires. This system just uses these plugs. So you'll take out your brake light behind your Sienna, and then you'll find very similar plugs to these. You'll just undo those and then plug these into those that will reconnect that circuit. So your tail lights will work and brake lights will work like normal on your vehicle.

But then when you plug in a trailer it's also going to send those lights back. So other motorists can see whether you're stopping, turning or driving at night. This will provide up to five amps per circuit for your stop and turn lights will also provide 7.5 amps per circuit for your tail lights. This four-pole flat connector can work with any of the four-pole flat trailer connectors that you might have on your trailer but it can also be adapted to work with a five pole six pole or seven pole wiring system on different trailers. You'll just need those adapters that are sold here at

We've got plenty of options for you to get that connected so that no matter what kind of wiring you're working with this will help to get you connected there. Now, as far as getting this installed it's a pretty straightforward process. They do include it's very detailed instructions to walk you step by step through how to get this all installed but just a really quick, quick rundown. Like I said, you'll pull out your tail lights, get these plugged in. You'll run the yellow wire over to your driver's side through the same process, get that plugged in.

We want to mount this box. They do include some double-sided foam here for you. So you can get that mounted to a solid location. You'll want to mount your ground here. They do include a self tapping screw to get that mounted to a metal surface. And then your black wire is going to connect to your battery, which is over on your passenger side. They do include some jumper wire to extend that to get it run over, then you'll connect your jumper wire to your fuse holder here, put your 15 amp fuse in at some point not right away, but the instructions we'll walk you through that. That's just to help protect your system from any power surges and that sort of thing. And then you'll get your fuse connector mounted onto your battery posts using the ring terminal there. It also includes some ties to help you organize your wiring. So like I said, very straightforward process especially in your Sienna with the battery being in the back is going to be much easier than with some other models where you have to run this all the way up to the engine compartment. So definitely a project that you can do on your own over the weekend. You don't need to be a mechanic. I did something similar. I used a similar wiring harness for my wife's vehicle. It took me probably an hour or so to get it all set up and doubly a lot better than having to cut into your wires. You don't have to worry about voiding your vehicles warranty and that sort of thing. So definitely a nice system. If you're wanting to add that four pole trailer light signals out onto your send those light signals to your trailer this is going to be a great system for you to install. So that's going to complete our look for today. Again, I'm Michael with Thanks for watching..
