‘01 QX4 > ‘99 Pathfinder Front Seat Swap

That looks right. Neither one of the circuits from the fusebox will draw any meaningful power, probably 10~15 milliamps for the logic supply and microamps for the ignition wire. So while there's nothing wrong with using a splitter-type fuse tap to provide a separate fused output, it isn't really necessary. You can use a blade type to tap the output side of the two existing fuses:

Just make sure to put the blade on the side of the fuse that's "cold" with the fuse removed.

I like the idea of the blade tap. I’ll order a few, get them installed and post the results.

Is 18ga fine, or should I go to 22ga?

Thanks again!

You could even use 24AWG, there's little-to-no current flowing in either one of them. Larger never hurts, of course, but whatever you have on hand will do fine.

I added those wires where you said too and the seat works like a charm. Thanks again!

You're most welcome. Happy (and comfortable) motoring!
