Greetings. I am rebuilding an old st-6. This unit has the 425 shift board in it and was prewired by Hal. What I would like is a copy of the wiring diagram, so that I know where the 2 loose wires go. I have remove all the mods that were done and now have it wired to what it was when new. Any help with this would be great. Thanks. Dave VA7DG
