Default Fuse location for 2015+ powered seats

I just finished swapping out my WRX premium seats with seat heaters to the 2018 OEM Recaro seats. Everything fit perfectly except for the black plug underneath the driver’s seat. Since my original seats weren’t powered I’m missing the one plug that goes into the seat that allows the motors to adjust the seat position. Unless someone can direct me to a harness I should buy can anyone tell me the location of the fuse that controls the powered portion of the seat in your limited WRX/STI? I know the seat heater fuse position is 17 using a 15A fuse but I don’t see a powered seat fuse in the diagrams. If I can use an add-a-fuse somewhere to power the seat I may go that route. Thanks in advance for your advice!

What exactly did you do?

"I just finished swapping out my WRX premium seats with seat heaters to the 2018 OEM Recaro seats."

Install a heater element and wiring <or> install an entire seat?

Just asking to clarify.

I installed the entire seat and plugged in everything from my car’s seat harness to the seat itself. The only thing I can’t plug in is the black plug underneath the seat which powers the adjustment.

The power to the driver's seat comes from/through the power window circuit breaker ("PWCB").

Per the 2015 FSM:

MB-30 / SBF-4 (B) is the start point.

SBF-4 shows as a 30-ampere fused circuit.

From MB-30 to the PWCB, the wire is black with a white stripe. From the PWCB to the power seat control connector, the wire is white with a green stripe. The other side of the connector would be a black wire direct to ground.

The connector to the power seat control itself is black and the power in is a red wire and the ground is a black wire. This is what is also shown in your picture above.

There is however no clear delineation between the Power Window System diagram and the Power Seat System diagram that from MB-30 / SBF-4 (B) the harness splits into two leads. None-the-less, assume that this is in fact the case.

Now to find where the PWCB is located.

Wow that’s a lot of good info. Thanks so much. I guess my next step is to find PWCB.

I’m wondering if I can just simply tap into a 12v though. Would that work and be safe?

The power window relay is located within a relay-holder, passenger room side, behind the glove-box.

Again, the schematics don't show a split from the PWCB. If however this is correct that it does, then running a same or one size larger gauge wire to this connector might be adequate.

Please note that I am not make any confirmed statements of any kind and cannot be held liable for your modifications, should you so choose to do so.
