And this would need to be soldered to/between the very thin black and red wires. Doing this insitu would require a surgeon’s skills. Looks like it would be spaghetti-fest removing all the connections. I may just pay you a visit because there are usually gremlins hiding in the weeds. But I will order the resistor if that is what works.
