Electric steering wiring help

[Robodent]

Hello
I’m wiring the electric steering unit on my truck and the schematic provided does not show a blue or yellow wire in it. I have all the wires provided and a blue and yellow as well and was wondering if anyone has come across this with the Electra steer unit. Thanks for any help or direction you can point me in. Rob

I think I read somewhere that they are not used for our application, but can’t remember where I saw that.
