! To prevent a short-circuit, overheating or mal-
function, be sure to follow the directions
below.
— Disconnect the negative terminal of the
battery before installation.
— Secure the wiring with cable clamps or ad-
hesive tape. Wrap adhesive tape around
wiring that comes into contact with metal
parts to protect the wiring.

through the blue/white cable. Connect this
cable to the system remote control of an exter-
nal power amp or the vehicle’s auto-antenna
relay control terminal (max. 300 mA 12 V DC).
If the vehicle is equipped with a glass anten-
na, connect it to the antenna booster power
supply terminal.
