I bought the XO Vision 1742bt and have a Ford Sport Trac. Could you tell me where to connect the Amplifier power control, Back sight off, and Brake wires?

Additionally, I have three wires remaining on my factory harness (amplifier ground, dash light illumination, and dimmer ground) and do not know if these attach to the unit or not.

I am very excited to install this unit and any help would be appreciated.
