Except RT models
Your vehicle is equipped with a
trailer lighting connector.
On RT models
Your vehicle is equipped with a
connector to install an optional trailer
lighting connector that mates with
your vehicle. You can get this
optional connector from your dealer.
Refer to the above illustration for
wiring information.
We recommend that you have your
dealer install a Honda wiring harness
and converter. This harness has
been designed for your vehicle.
Since lighting and wiring vary with
trailer type and brand, you should
also have a qualified mechanic install
a suitable connector between the
vehicle and the trailer.
