The two wires connected to my stock Spektrum 150A esc have come undone. Is there any diagram showing where I should solder these back on?

The black wire follows the black lead and the red follows the red.. I believe they are soldered with the esc leads on the board!?

Sorry, now rereading my post my description was terrible. The two wires that have come loose are the ones that attach to the actual cap pack. Both the red wire and black wire are detached from the cap pack itself. I am unsure as to where on the cap pack you solder the wires back on.

Yes polarity MUST be correct. Find a picture of another same ESC/ Cap Pack for reference. I don't have that ESC. Or I would send the pix it here. I did understand your first post . And this is a common problem with that ESC and OE cap pack. You can also just buy a Castle Creations Cap pack which may be a better choice with better higher rated caps. Good luck.
Edit:
Some have warranteed the whole ESC with HH for this reason. You also need to secure the Cap pack better so it doesn't shift and bounce around. That is why the solder joints separate. But I still say a quality soldering job is needed, which the OE cap Pack does not have is the main problem here.
Firma/Arrma has no excuse for poor soldering. Done right a solder joint will not break from stress. It sucks. One reason I don't like the Firma ESC's. I stay away.

Thanks for the help!
FWIW, I prefer to mount cap packs to the truck. Somewhere solid so it's not bouncing around with the wires. Flexing those little wires constantly is what breaks them. Even attached to the battery wires, the entire cap pack is bouncing around all the time. Strange that I see a lot of the smaller ones like that.
