I’m installing a lcd ColorDMD on my Metallica Pro (metal back box) right now. I have everything installed but I cannot find the ground wires to reattach as stated in the directions. The only ground wire I see is attached to the metal bracket in speaker, see pics of original dmd before I took it out, there were no ground wires attached: should I take off that ground wire on speaker and attach to dmd? Sorry, noob at this-

Ok, I took it off from speaker and attached to bracket. Hopefully that does it-
