Wiring
Disconnect the vehicle’s battery to avoid an electrical
short. Then connect the ground wire to the KEYLOC.
Make the ground wire short, 24” (60cm) or less, and
connect it to a paint-and-corrosion-free, solid, metal
area of the vehicle’s chassis.
Install a 2A fuse
between the KEYLOC and the power source. The
fuse should be within 18” (45cm) of the power source
and in-line with the harness’ yellow power cable,
which is connected to the KEYLOC. Keep the audio
signal cable away from factory wiring harnesses and
other power wiring. If you need to cross this wiring,
cross it at a 90-degree angle. Connect your source
unit’s speaker outputs to the KEYLOC speaker
inputs. When interfacing into factory speaker wires it
is recommended to splice and solder, if you need to
use wire taps make sure you use proper sized wire
taps to ensure a solid connection.
