Fuse location for 10A TCU pin# 17 & 18

Does any one know where to locate 5A and 10A fuses, which are used for 12V+ for TCU unit? These are pins #17 and pin #18 on TCU connector.

Here is what I am trying to do. I have TCU and ULF and I am trying to replace the two units with Combox. Well, this morning I measured voltage going to my Combox (after the PnP cable), and I am missing +12v on pin #1. Pin #1 is fine.

I have a feeling that the 10A fuse, which is for pin# 17 is blown.

Any suggestions or fuse diagram, please. Is it located in front or back of the car?

Thank you.
