Dakota Digital to Koso signal wire

I know this has been hashed over many times before on the forums but I just want to clarify the wiring. I am assuming the Koso only needs on wire to operate the speedo. Ive seen reference to not using two wires that would normally go to the wheel speed sensor. What is the correct wire color to connect to the Dakota digital. Also the speed 2 connection should be utilized with a 128k setting? Thanks

Here's how I hooked mine up:

Koso: Connect the white wire to the Speed Output #1 on the DD GPS. The settings I used on the KOSO were 25 sensor points and 310mm tire diameter. Black and red wires are not used.

GM VSS: Purple/white wire to Speed Output #2 on the DD GPS. Set the DD GPS to 128000 pulses.
