Unswitched power is anything on the battery buss in the interior fuse box.

The battery buss is the two top rows of fuses.

Switched power is the next two rows of fuses.

Aux power is the last single row of fuses.

Another source of batt power is the pure black wire that feeds the ignition switch. It's in a connector on the ignition switch pigtail that has a black/white wire with it.

Pure black has power 24/7. Turn the key ON......power goes from the pure black......thru the switch......out to the black/white wire (IG1) and also to the Black/Red wire (IG2)

Black/white feeds the row of fuses that the ENGINE fuse is on. Black/Red wire feeds the row of fuses just below the row that has the ENGINE fuse.

IG2 loses power if the key is HELD to START or you go to ACC.

Seems to me you need to find out what amp fuses the exeight used for those seats and then find a fuse with enough ooomph for the seats. Or wire in a wire from the engine bay to the interior with a inline fuse or??????

Anyway the jpg attached shows in red the batt buss with power 24/7 and the green and blue row of fuses that are switched but remember the IG2 row loses power if the key is HELD to START. And we all know about ACC so I'll let that go.

Plus all the fuses in the engine bay fuse box are on the batt buss 24/7
