You may still have an air flow issue as you have severely restricted the intake air volume from its original capacity.
Thats what I'm thinking plus now it's ingesting its own heated air.

1 Return intake vent NEEDS to be the same size as the "original" opening.
2 The furnace will now pull the heated air from the "new" output vent right back into the furnace.
While you may have "corrected" the over temp for now you most likely will have it again and at the same time will use more fuel and battery to do the job.
To correct both problems you need to do the following..
1 Put original return ven back into place.
2 Locate a NEW place for the output air vent SEVERAL FEET away from the return air vent.
3 READ THE MANUAL! The furnace manufacturers actually put the correct ducting info into the manual for how to install. It is specific for the BTU SIZE of the furnace.
Make sure that your furnace TRULY "needs" three (or more)duct connections. Otherwise you could be hiding a serious issue with your furnace.
This is not the place to play around and hope you fixed it, a overheating furnace is a fire hazard and needs to be addressed properly.
