HELP! Marantz 2230 - wiring under P300 board

[tinwhiskers]

I am a big dummy and I forgot to take before photos of the wiring under the P300 MPX board in my 2230. There are two posts on the underside of the board that had a wire going to each of them. They are labeled J316 and J30(5?)

Bottom of mpx p300 board

I think that it may have been purple to j316 and green to j305, but I don't want to trust my memory and the service manual isn't being helpful.

Thanks for anything you can do - especially a pic of what it should have looked like before I took it apart .

Nevermind. I just found this gem over on another thread!

The last 3 2230's I did were hooked up this way. (I take lots of notes)

J301 (White) center of orange shielded cable
J302 (Black) shield of orange shielded cable
J303 (Orange)

J306 (Brown)
J315 (Red)
J314 (Blue)
J313 (Black)
J312 (Green)

J307 (Gray or Brown) this is near the front panel

These wires come through the hole under the P300 board:
J305 Bottom of board (Green)
JXX or J316 Bottom of board (Violet)

Hope this helps you should probably trace it out to be sure.

Two wires, very small sample space.
