Water carbon heated front seats

I’m having trouble wiring these heated seat basically the pads plug into these white connections
But I just don’t know where to tap into for the positive I’m very new this stuff lol
I know the black wire is just a ground that can be grounded to a bolt somewhere
But don’t know where to tap into
Would love some pointers and also I have this for two seats

 

You need to run the fused power wire and the ground out to the battery. Ideally the fuse should be within 12” of the battery, or a distribution block.
