Martin Logan Motif help please

Bought a Motif, thought the els panel was intact, it isnt. Before I order a new panel I thoughtc I might try to fix this one. Problem is, no electrical connections survived a previous shipping disaster on the panel. The rest of the speaker also has damage but I can repair/ improve on it. Can anyone send me some info on how this panel connected? So far all I can make out is a black wire was attached to the left rear of the panel if you were looking at the speaker. Any help is appreciated.
Actually anyone who can tell me the wire placement for their ML would be helpful.
