1 – Street Icon LEDs: connection and setup
Question:
I have an MXS1.2 Strada / MXG 1.2 Strada / MXP Strada with the optional Street Icon LEDs.
How can I activate my Street Icon alarm LEDs according to my car/bike signals?
Answer:Street Icon warning LEDs are not strictly connected to a specific analog input: these LEDs can be freely
linked to any analog/digital input of the AiM dash or also to channels received through a data bus
available on your vehicle (CAN, RS232, K-line).
Street Icons featured by each AiM dash are listed here below:

In the next pages the physical connection, with related wiring diagrams, and the software
configuration are explained for all the available alarm icons.
On newer vehicles these parameters might be supplied by a data bus.
Check on AiM website (www.aim-sportline.com) – Documentation Area - ECU Connections – StockECUs, which parameters are available for your vehicle’s ECU driver. If they are included in the list, jump
directly to Chapter 3 for the configuration, otherwise refer to the following Chapter 2.

2 – Physical connection
Here follows explanation for the physical connection to the vehicle signals, when they are not comingfrom data streams broadcast by the vehicle.

2.1 – Turn lights and high/low beam signals
Head lights and turn lights are generally signals that raise to 12V when activated, otherwise they sit at
0V. These signals are used to feed the original instrumentation unit.
Turn lights• pick the turn lights signal from the original instrumentation connector• connect it to one of the analog channels of your AiM dash (23 pins optional wiring harness),using Pin1 of the Binder connector.
If signals for right and left directions are separated and are going to be used with an MXS1.2 Strada,
with one LED dedicated to turn lights, it is recommended to join the two channels together. To do thisuse two diodes (1N4148) as in the diagram below:High beam/Low beam
• pick the high or low beam signal from the original instrumentation connector• connect it to one of the analog channels of your AiM dash (23 pins optional wiring harness),using Pin1 of the Binder connector.

2.2 – Fuel level/reserve signals
Fuel reserve warning lamp can be associated to an analog signal coming from the fuel level sender orfrom a reserve switch; this last is very common on bikes without fuel level indication.
Fuel• pick the fuel level/reserve signal from the original instrumentation connector, or from the fuelpump connector, where the sensor pins are available.
• connect it to one of the analog channels of your AiM dash (23 pins optional wiring harness),using Pin1 of the Binder connector.
Fuel level – connection notes
Fuel level senders generally output a variable resistance signal, thus an additional pull up resistor has
to be added. The value of this pull up resistor, shall be 9 times greater than the maximum value thefuel sender shows when measuring its resistance (Ohm) at full and empty levels, with ignition key off.
Should this value not correspond to an available resistor, select a value rounded off by excess.
The pull-up resistor is to be bridged between Vref (Pin4) and the Analog Input (Pin1) of the Channel‘sBinder connector (23 pins optional wiring harness).
Picking this signal from the original instrumentation connector, the sensor ground wire (GND) may
not be available: in this case use the common ground and link it to Pin 2 of the Binder connector.

Fuel reserve – connection notes
Fuel reserve signals generally output a variable resistance signal generated by an NTC thermistor. This
specific sensor requires a current loop to work, thus an additional pull up resistor has to be added.
The value of this pull up resistor, shall be in the range of 40-80 Ohm and this must feature a maximum
power of 3W due to the high current flowing through it.
The pull-up resistor is to be bridged between the vehicle switched power (12V) and the Analog Input(Pin1) of the Channel‘s Binder connector (23 pins optional wiring harness).
Picking this signal from the original instrumentation connector, the sensor ground wire (GND) may
not be available: in this case use the common ground and link it to Pin 2 of the Binder connector.

2.3 – Oil pressure/level signals
Oil alarm warning lights are generally driven by switched to ground signals when activated; whenreleased they are pulled up at a voltage of 5V or 12V. So they act as digital ON/OFF status signals.
This warning lamp can also be linked to an AiM oil pressure sensor, to be chosen among thoseavailable in the AiM catalogue. Check them out on AiM website (www.aim-sportline.com) – Products –Sensors.
Oil pressure/level switch• pick the low oil pressure/level signal from the original instrumentation connector, or directlyon the sensor/switch pins
• connect it to one of the analog channels of your AiM dash (23 pins optional wiring harness),using Pin1 of the Binder connector.

AiM oil pressure sensor• Connect the sensor to one of the analog channels of your AiM dash (23 pins optional wiringharness). If using a customized harness, be sure to connect signal, ground and Vref (5V) or Vbat
(12V) power – according to the sensor used.
