General Connections
Connecting Power/Ground
The X20L has 5 power connection points, four of these are high current and can be connected to a
fused battery power or switched power source. One of them is Logic Switch / Ignition Switch power
and used to switch the power gate so that current is able to flow from the 4x High current 12v pins
into the Device.
If driving motors or solenoids which pull a lot of current then ensure the correct amount of pins are
connected. Each pin on the X20L is able to sink around 14 amps of current, so if driving multiple
solenoids that pull 20+ amps total, ensure at least two high current 12v pins and two power ground
pins are used.
Internally A8/A9 are linked, as well as B1/B2. These can either be used to provide extra current on a
supply, or as a way of providing switched power to additional loads through the loom.
Pin A2 (Ignition Sw) is for a 12v low current ignition switch supply to enable the power gate on the
X20L internally, this is required on all installations.
Power Grounds are joined internally and the X20L must have at least A33 and B26 connected. If
driving lots of Low Side outputs then connect A34 and B27 also to handle the current loading.
NOTE! Power Grounds are designed to conduct High Current loads – Do not mix Power Grounds with Analogue
(AN) Grounds.
