WTB Egret 29 parts

Looking for a few parts to complete this Egret 29.
Need the back panel which you can see is missing in the photo.

Also could use this harness


Any information would be great.
thanks in advance.

What exactly does that harness do? I have it in my cab, but it's not connected to anything.

As of right now everything in the cab is connected to this harness. The cab is missing the second half..

I believe the second half of the connector is jamma to egret.
Resorting the cabinet back to factory would be nice, installing a new jamma harness would be easiest.
please correct me if i'm wrong.

If you google "egret 29" the first link that is available is called "my egret 29"

there's a small section about this connector..all it's reads is

"The JAMMA connector wire contains this weird connector. Perhaps there are other than JAMMA connectors available for Egret? The small white connectors with black wires are for sound - connect the plug for stereo, disconnect for mono."

Even on Yahoo Japan, I rarely see Egret 29 pieces up for sale. I'd probably just wire up a new JAMMA harness and keep looking for the connector you need. You might get very lucky locating the pieces, but at this point I'm guessing it'll be very difficult.
