NOTE: Make sure the engine is off and accessory power is off before proceeding.
•Step 1: Locate your Fuse Box
Fuse boxes and fuse types vary not only between car models, but also on year
and variant.Check the Car Manual to find the fuse box location and confirm
the fuse type.
•Step 2: Identify which fuse is ACC & Battery
①Battery Wire (YELLOW)
To identify a fuse for the battery connection, turn the ignition switch to the
lock position. Look for a fuse that is live (allows electricity to flow) even when
the ignition switch is in the off position. You can identify the fuse by applying
a fuse/circuit/voltage test device when the engine is off. Place the tip of the
tester on the exposed metal part of the fuse.
②ACC Wire (RED)
To identify a fuse for the ACC connection, turn the ignition switch to the ACC
(Accessory) position.Look for a fuse that is live when the ignition switch is in
the ACC position but off when the ignition switch is in the off position.
•Step 3: Locate a Ground point
To identify a suitable ground point, use circuit tester in continuity mode.
Locate a screw with direct connection to the vehicle body and check for a
good continuity reading between the screw and the vehicle body, this should
be < 0.1 ohm.
