Thank you so much for the reply... I have two questions about how to proceed.

Just to confirm, the blue and black wires at the top of the first image are indeed from the Tuner Plug. I used a print out of the image you included below from the FAQ to confirm my suspicions. Thanks for including it for completion sake.

Question #1:
Short term. The empeg works with the current wiring. If I were to splice the blue Amp Remote and the black Ground from the Tuner Plug back into the matching wires from the sled, the Tuner should work?

Question #2:
Going over the diagram I seem to remember the yellow Memory wire had a black plastic piece that I assume was the "Filter and Fuse" shown in the diagram. That is sadly long gone. If I could find a new wiring harness for the empeg, would this revised diagram I am attaching be the correct way to hook everything up?

I'd love to take this information back to the original installer, but they are no longer in the Car Audio business.

Again, thank you for taking the time to help!
