Mopar electronic ignition?

Moisture absorbent is the last thing you want in there. I would think any circuit board for under-hood use would have "conformal coating", which is a clear coating to keep out moisture and corrosion. That doesn't appear to have it. I think the black potting served that purpose. That large transistor (TO220 case) should be attached to the case for heat rejection. Some have found them just pressed lightly against it. I imagine the top side has a fake TO3 transistor. That design could work fine if they didn't cheapen it so much.

I hope the new "Genuine Mopar" part isn't from the same Chinese factory. There are many fakes out there. The give-away is they all have the same printed SN. Sometimes the Chinese copy too well.
