Hello, I'm digging into a failed IDM to see about what's involved in repairing it. I have traced the issue to these two blown resistors. Along with these I'm going to change out the transistors also linked to them, actually all of them in this area. However I can't seem to find their values and internet sleuthing seems to have revealed nothing useful. Is there anyone here who has specific information on these resistance values. Or better yet has a board view, that would be fantastic.
I don't have an answer but I'm following, this is great stuff. Please continue to update and document your repair because this seems to be pretty common issue. Thanks!

Well, it's been a while so I'll post what I collected so far.
Since the denizens here are unwilling or unable to assist, I'm going to quote Thanos,
"Fine, I'll do it myself..."
I was at the salvage yard and came across a f350 with a 7.3 and nabbed the IDM. For the sake of information and repair of these units I bought it:
and opened open revealing the information needed:
These resistors ratings are determined by the numbers on them, the watts are determined by their size, and the ones with no numbers are capacitors which values are also determined by their size. I'll desolder the components from the bad board and make a list of what is what and what goes where. I'll get these parts on order and once they arrive I'll likely post a video of the repair on my TikTok channel thetinkeringmechanic and a longer more in-depth video on my YouTube channel of the same name.
