Fuse box F113 connection.

Anyone know BMW 1997 740iL wire from F113 under the passenger seat goes to F29,F30,F31?
According the electrical diagram yes but in reality? There is not any power on this fuse in engine compartment. Please help if you know.
Thanks

All the fuses under the passenger seat (F107 to F114) get power from the 200 amps fuse located in front of the battery, if no power is found on fuses

F29,F30,F31 then probably F113 is blown.

F113 is good, I don't have power on F29,F30, F31. I cannot trace the wire goes from F113 to fuse box engine compartment. Do you know the wire should go to the engine compartment box, or somewhere else?
Thanks.

There are 3 wires coming out of F113, the heaviest goes directly to the E-box feeding power to F29,F30,F31 and........F81(40 amp blower relay red fuse), the other 2

wires send power to the Light Control Module and to the power cut off relay.

Check for continuity between F113 and the fuses mentioned above in the E-box.

I checked continuity between the Fuse F113 and Ebox there is no continuilty, and no power on the F29, F30, F31. Do you think it might be the broken wire inside the harness, or it goes somewhere else for example to the ignition switch. thanks for your answers it really helps. I will attach the pictures if possible.
