Unhappy FUSES of Seconary Air Pump. P0491-P0492


I have a 2000 BMW 740i. I shorted the circuit and blew out the fuse(s) of the secondary air pump when I replaced the oil cover gaskets (the positive terminal touched the body ground). Now, the car sends out the P0491 and P0492 error codes.
I remember to read that the fuse is somewhere in the passenger seat area. Please someone confirms and gives me more exact location of the fuse. I could not locate the fuse in the fuse box. It supposed to be 50 AMP? I need to fix it to pass the emission.

Many thanks in advance.
