I have a 2020 Rav4 XLE, I have an empty slot in my fuse box. I have an accessory that requires 20 amps. The vehicle has low profile mini fuses, but all fuse adapters I find online are 16 gauge. I would need a 12 or 14 gauge adapter. I can't find any online. How am I'm going to be able to power this device when the vehicle is on. The empty slot does provide power when the vehicle is on online and vehicle manual doesn't state how many amps it can handle.
