Hi everybody!

I am Zsolt, from Hungary. I have a problem with my old, 2004 Mazda 3 (1.6). My passenger fuse box get soaked. It got water, so it is unsalvageable.

We need to replace the whole fuse box with the BCM module, because it is responsible all comfort electronics (such as power window, that also died).

The new price of a fuse box is very high for me, so I am looking for a used parts. I have some options, but the part number of the fuse box in my car is BP4K 66730 C. Fuse boxes which I found at car wreckers has different part number, exactly that: BP4K 66730 F
Is it good for me? May I buy this parts and it will work for me?

Another question is, if I replace the fuse box, should I setup (teach) the electronics again, for example immobiliser?

Thank you for your help!

Best regards,
Zsolt
