Replacing Motion control board

I recently replaced the control board with one Langmuir sent; the old board has a black box with red underlying rectangle ; My question is, “ Does the new board need the black box w/red underlying rectangle??? Top image is old motion control box

It didn’t come with one

You should be able to pull the red relay board and move it over to your new main board.

I think it’s fitted down with six pins, it should pull off.

That box is the Torch firing relay. You need to transfer that to the new board.
