Where Does T-One Vehicle Wiring Harness Hot Lead Connect on 2025 Kia Sportage Hybrid EX

Question:

I have a 2025 Kia Sportage Hybrid EX. I would like to install the TK32VR wiring harness. I plan on towing a small trailer and will not need a brake controller. My question relates to running the power wire to the battery. Apparently the battery is under the rear seat, but there is supposed to be a POS+ terminal at a master fuse box under the hood. Have you installed this harness in the hybrid and confirmed compatibility? Where did you attach the power wire? Thank you,

Hey Les! We have not had the chance to install the T-One Vehicle Wiring Harness # TK32VR on a 2025 Kia Sportage Hybrid yet. However, I can confirm it will fit. Also, your question about the power wire is pretty common for hybrid vehicles. You can run the power wire to the 12V terminal you referenced (probably the easiest way to do it) or directly to the battery under the seat.

Will you be using the wiring for a trailer or for an accessory with lights?

My intent would be to use it for a lightweight kayak/bike trailer like a Malone Microsoft. Can the wiring be installed after the hitch is in place? Thanks for the reply.

@Les of course, you can definitely install it if your hitch is already in place. Any big plans biking or kayaking this summer? Stay safe out there.
