Power to electric seats

[seanmc1970a]

Spring has sprung and winter ideas need acting on

I've bought a couple of Mazda rx8 seats and am half way through fitting them, holes are drilled out and happy with the position.
So my mind has now turned to supplying them with power, they don't really need power, but would be nice to have the heated seats for winter.

What would be the best approach or could anyone point me in the right direction

Seats have been tested on the bench and have extended the wires.
Lumbar, seat position heating all have different wires, so plan is to next run those wires to fuses then tap into to the fuse box at fuse 7

Air bag wires have been taped up
