6.
Label and route the DC Power Cable’s white wire to the vehicle’s fuse box. Tie and stow as necessary
so the wire remains out of the way of casual contact and wire chafe is avoided.
NOTE
The Control Head wakes up the radio via the CAN port when power is applied.
However, connection of the white sense wire may be needed in future configurations
that do not use the Control Head (e.g., Data-Only applications). Therefore, it is
recommended that the white wire be labeled, routed up to the vehicle’s fuse box,
coiled, and stowed for possible future use rather than be cut from the DC Power Cable.
7.
In the engine compartment, strip the Time-Delay Relay’s black wire and crimp a 3/8-inch ring
terminal to the wire.
8.
Locate a nearby section of vehicle chassis ground and strip the area of any paint or dirt to expose a
bare metal surface.
9.
Drill a hole as necessary and connect the relay’s black wire to chassis ground using a self-threading
screw.
CAUTION
Do NOT connect the relay’s black wire directly onto the negative terminal of the
battery!

1.
Cut the red (positive) wire of the DC Power Cable to a length long enough to reach the Fuse Block
plus length for a service loop.
