3.3) Connect to fuse box
Identifying the right fuse location to pull power from:
Using a multimeter set to check DC voltage, probe ground from
the vehicle where available, and probe power from the top of
the desired fuse. A suitable location will have constant 12V, and
the fuse rating must be higher than or equal to the new fuse
you have purchased for IVS.
Remove the fuse using needle nose pliers, and then probe
power from each side of the open slot. The side with 12V will be
the load side, and the side with 0V will be the draw side (see
diagram on the right).
When inserting the fuse adaptor, take care to insert in the
orientation described to the right. In other words, the load side
as described in the diagram must correspond to the side of the
fuse slot which provides constant 12V. This will ensure that the
power will cut if the fuse blows.
IMPORTANT:
Check which vehicle functions go to which fuse
location (diagram is usually located on the plastic cover for the
fusebox). Care must be taken to ensure that power for this device is
not pulled from safety-related vehicle functions, such as: airbags,
anti-lock brake systems, traction control, and collision prevention
systems.
