Hey Al, Bernie provided me with diode 91161710801

Which should work. Keep in mind there is a dedicated hot lead going to the LED at 1:00 (red) and black wire going to the blue wire using the light blue connector. I have tried inserting the resistor above on the red and white and then on the black and the alternator will only put out 12.5v with it installed at idle. As you can see, I did not hack into the thin red wire to insert the resistor but may need to. But again it only connects to the LED and not a bulb so that is probably part of the issue. Don’t have a bulb holder for the old bulbs I have. What is the proper orientation for the resistor, asks the electrical idiot? On the female side of the resistor, there is an interesting occult pictogram with a circle with a triangle with a T at its top which would suggest orientation to a lessor idiot. Question one, on which color wire should the resistor go, and 2. What is the orientation of the resistor on said wire? 3. What to do about the difference in resistance between the current LED versus the standard bulb or.... 4. Should I first try wiring in a bulb and bypass the LED, but how without a bulb holder?
Just a tidbit, as an experiment, I added a way to high voltage bulb because it had a bulb holder which stayed illuminated with the car running. When I turned the ignition off, the car continued to run until I disconnected the bulb.
