Took some pics of how the USB broke. Not sure if the P72 daughter board lines up differently than the P61, but I had to take a couple extra measure than Xenocron mentions in his write up.
The USB socket (how it should be)
How it is now
Surface mount is suck
My board that the USB is NOT broken on. Showing the USB cord shaved down and taped up for clearance (Which is kinda shitty design IMO)
The daughter board and how it all lines up
If I lay the board all the way down, that chip contacts with the USB cord
So this is what I decided to do differently from Xenocron's instructions:
I put two of small screws that would hold the daughter board in, into the case without the board. Using these to prop the board up.
I then put the board in, and held it in by the other two screws, just loosely screwed in.
I was then going to put the cover on backwards, because the center hole is offset. But there is that plastic anti static cover inside of the lid, and I wanted that to line up with the daughter board obviously.
So the lid had to go on facing the correct way. But I obviously cant put a screw in it, because the screw is under it already. If this were MY ECU, I would have cut the recess out, so that the lid can sit flush, but its not mine, so I cant. So it does bulge up in the center. But with the screw being under where the pressure is, I dont see any damage coming from this...
Heres the bulging
