Put a 4.7k resistor between the Yellow wire and ground. Use a 1% surface mount resistor.
Thanks Chris. I was going to post that I guess the yellow wires just can't be seen in the plug now (I haven't pulled everything apart yet), but forgot to.
That said, I do have two questions:
1) Upthread there was discussion about using a single resistor instead of 2. You were going to try it out. Did you ever try it? Did it work?
2) Anything particular for a 4.7k 1% resistor? Am I correct in guessing that any power rating would be fine? It looks like Digi-Key has 125 different 4.7k 1% surface mount resistors to choose from.
