Is There A Plug And Play Harness Available For My 2025 Toyota Crown Signia?
Updated 08/04/2025 | Published 07/31/2025
Question:
Is there a trailer wiring harness for a Crown Signia that doesn’t require splicing? Or at least a kit with specific installation instructions for the Signia? The harness would be kept inside the spare tire cavity.

Hey James,
There is not a plug and play option for the 25' Crown Signia, a splice in option is the only available. We have the Curt harness # C59236 for your vehicle. The instructions are also universal since any splice in harness can be used on many different vehicles. I have still attached those instructions for you below to get a better idea of what the install will look like for you.
Are you looking to tow a trailer with that vehicle?
