Wiring heated seat kit

Looking to purchase this heated seat kit for my tacoma to go with my clazzio covers.
Can anyone assist me with how to wire?
I’m told i can use a fuse tap? Which slot would work for power?
Also would i just connect both positive wires together and then connect the fuse tap to that? Anyone able to help me out? I have also read about using a relay but i have never wired with one of those before. Anyone able to give me some assistance ?

I’d first took directly to the battery and see how many amps they draw, or maybe the paperwork lists it. That will determine your course of action. Generally with heated seats they are a heavier amp so I’d run a dedicated circuit. One trick I use is that you can use the power window fuses for back windows if you have a double or regular cab, I believe they are a 30 amp circuit. If you have a double cab, I’d just run a separate hot wire fused at the battery.
