How to use (demo videos)

• If K3 or K4 ACC jack not in use, connect plugin directly to K3 or K4 ACC jack as shown below:
  

• If you already have a Y-BOX v2.0 or v3.0, connect to any available jack on Y-BOX (except the jack labeled "To AMP AUX" jack):
  

• If the ACC jack is already occupied, add a Y-Cable to your order, or order a Y-BOX.

• The new Y-BOX v4.0 has the Auto On circuit built-in, so the K-ON plugin and Y-Cable are not needed, as demonstrated below:
