Sometimes, a good box of crayons and 4 fingers of whiskey helps my troubleshooting endeavors!!!!!!!!Thanks for posting this. I thought this was how the signals were routed but you confirmed it for me with the colored paths. And I just now fixed a 449 with a bad L39. (Not the same 449 I had thread on a few weeks ago.)
We now return this thread to fixing the 457 Hakweye351 is working on.
