This entry represents a couple of days of work on an electrical project that has probably taken far longer than it should have. (But I just love engineering projects like these -- I can't help myself!)
1. Decided to add a second D-sub connector to the resistor box for the annunciator light panel, instead of simply running the wires out the side of the box. Cut the hole and attached the new connector.
2. Finished soldering the various resistors onto the PC board for the annunciator light panel, cut 18 lengths of 22AWG Tefzel wire, soldered one end of each to the appropriate pad on the board, crimped D-sub pins on the other ends, and wired the connectors. You'll notice in Photo 2 that the resistors are staggered up and down because of the tight spacing between slots.
