Wiring
The PSN-1 has 5 stripped wire leads:
1
Connect the
RED
wire to an isolated switched 12V source in your
vehicle. A switched 12V source goes ON as soon as “key on” power is
active. The circuit to which you will pull power from should be able to
support a 3 amp draw. Make sure this connection is protected with a 5A
fuse (not supplied.)
Circuits that share power with the vehicle’s stereo, ignition system,
ECU, lighting, or fuel pump should not be used. When in doubt, create an
additional circuit using an automotive relay available at any automotive parts
supplier. See the next section for a relay installation diagram.

The
BLACK
wire should be grounded to a solid ground source. The
best possible ground source would be the battery ground (-) post.
If other Innovate Motorsports devices are going to be daisy-chained
along with the PSN-1, it is recommended that all devices be connected to a
single ground point, ideally the battery ground (-) post.
3
Connect the
WHITE
wire to a headlight power wire (a wire that goes hot
with 12V when the headlights are on). This enables the display to dim
for better nighttime viewing. DO NOT CONNECT THIS WIRE TO THE
HEADLIGHT DIMMING WIRE. Connection to this rheostat type of
switch will cause the gauge to malfunction. If you chose not to utilize the
dimming feature, connect the WHITE wire to ground.

Optionally
, the
YELLOW
analog output can be connected to the analog
input of other devices such as data loggers or standalone ECUs. If this
