CAUTION!
As a safety precaution,
the +12V terminal of this
product should be fused
before connecting to the
12V ignition switch. We
recommend using a 3 Amp,
automotive type fuse.

Red: .............. +12V, (key on power). This can be connected to the same power supply you are using for your gauges, or to its own 3 Amp fused power
..................... source.
Black: ........... Engine ground.
Black: ........... Transmission gear position sender ground
Yellow: ......... Check engine light signal from your engine computer (if equipped).
White: ........... Lighting power from instrumentation/dash lights.
Violet: ........... Transmission gear position sensor signal.
Light Green: .. High beam indicator (this is power from high beam switch).
Brown: ......... Calibration set-up wire (only used during set up of gauge during installation). Momentary switch to ground.
Light Blue: ... Left turn indicator (this is power from your left turn signal circuit).
Dark Blue: .... Right turn indicator (this is power from your right turn signal circuit).
This will require checking the wiring diagram pertaining to the computer (ECM, PCM, ECU) that you are using. To activate the CEL, the yellow wire
to the gauge gets grounded by the computer. In other words, this is a ground activated circuit. If your vehicle is not computer equipped, then you may
simply seal the end of the wire, and do not use.
This will require checking your vehicle or aftermarket (if used) wire harness diagram. To activate the Hi Beam, the light green wire gets powered by the
hi beam circuit. In other words this is a power activated circuit.
This will require checking your vehicle or aftermarket (if used) wire harness diagram. To activate the Left Turn indicator, the light blue wire gets
powered by the left turn circuit. In other words this is a power activated circuit.
This will require checking your vehicle or aftermarket (if used) wire harness diagram. To activate the Right Turn indicator, the dark green wire gets
powered by the right turn circuit. In other words this is a power activated circuit.
The wire colors on this product were selected to best match the most popular aftermarket wire harnesses, steering columns, and GM vehicles to
simplify installation and wire color matching, though this can be used on nearly any 12 volt, negative ground vehicle.

Helpful tips to determine which of your factory wires are turn signal, and high beam:
If you have easy access to the wires behind your gauge panel (most easily done with gauge panel removed), you can use a simple test light. With
power turned on, you can turn on your left turn signal, and probe each, un-used wire and when your test light starts to flash with the turn signals, you
have found the correct wire. Repeat the same for the right turn signal. For high beam, you can leave power off, but turn on your head lights. Activate
your high beams, and use your test light to determine which wire has power. When you find it, deactivate your high beams to make sure the test light
goes out. If it does not go out, then you have not found the correct wire yet. When performing the above tests, make sure your test light has a suitable
electrical ground on the vehicle. A poor ground connection for your test light can adversely affect the outcome of these tests.
