Question:
I have a 2025 Honda prologue. It does not have a factory wiring harness. I’d like to add a flat 4 wiring harness for the trailer lights. Can you give me the exact part number? I’m looking for from your site. Thank you.

Hey Tracy. The Curt T-Connector Vehicle Wiring Harness item # C44FR is what you'll need to add a 4-way to your 2025 Honda Prologue. This harness is going to plug into a factory port behind your rear bumper on the passenger side. You'll be looking for a black connector with white filler blocks. Once you find it you'll need to push the red tab towards the white filler’s blocks and press the housing release to remove the dust cover. You'll then be able to plug the Curt item # C44FR directly to it.
I recommend using the No-Drill Mount for Electrical Mounting Bracket item # 18140 and the item # 18144 to secure the Curt item # C44FR to your hitch. This will not only put it in a conveniently accessible spot but also prevent it from being damaged.
You said you didn't have the towing package. Do you also need a hitch? If so the Curt Hitch item # C89RV is what I recommend for your 2025 Honda Prologue.
What kind of trailer are you pulling?

Hey Tracy, how did things go with the Curt wiring harness on your Honda Prologue? Did the connector behind the bumper match up the way it was described? Your update could make it easier for others adding trailer wiring to the same vehicle.
