Good morning, I bought a heated steering wheel on eBay. Part No. 78500-TLA-C110-M1 (V3682 HONDA CRV CR-V 2017-2018 OEM STEERING WHEEL LEATHER). it came with the switch, but it didn't come with any heated harness, control unit, cable reel, cable reel cord, relay... (I see that I need all this parts to do the installation, on the collegeHonda Manual. Where I can buy the missing parts that I think I need to do the installation. Much appreciated who can help me. Picture attached of the item I bought.
Thanks.
