Hi. I have a 1992 K75. I bought it from someone who let the fuel injection control unit get wet. It is very badly corroded and rusted in the circled areas of the picture I will attach.
The picture is a picture I found online, as I do not currently have a way of taking a picture.
My FICU is 0 280 000 332 Bosch 3 Zylinder
I need some high res or closeup photos of this area so that I can identify some of the components so that I can repair it, as there is no schematic available online.
Thanks
P.s.: I'm very good at soldering and I don't have the money to spend on an ecu yet. Please Help if you can

Its not really quite common to open them up, take high res close ups from an ecu for sharing purposes I guess.
However the K bike market is decently flooded with (used) parts. Now I do understand you dont have a big wallet, but after soddering you wont have a guarantee either.
I'd check for a used ecu.

if i had a million dollars and a schematic i'd still prefer to fix it myself than to purchase an ecu that is not the original very exact same one

There are several used K75 fuel injection control units with the correct Bosch numbers available on ebay from legitimate vendors. For the highest resolution possible, one could be purchase for around 100USD, the cover removed and the guts viewed in person.

I am not sure if you meant the very exact same oem number or the one that was in the bike itself.
However you could be the first to make a schematic for injection control unit repair.
Other than that i have this for you:

I recon from here on out further research should be possible.
