MicroSquirt.com read only forum (Jan.15,2018)

In the wiring page it says

NOTE: The wire labeled "Vref" is the +5V voltage source for the MAP sensor and the TPS sensor. This wire only connects to these components, so be very careful to not connect this directly to ground or (worse) +12V battery. Bad things will occur if you mis-wire this one - double check your work.

Now further down the page, about the 'ACCEL LED' and 'WARM-UP LED', it says to connect them as:
the longer lead of the LED you connect to a 330 Ohm resistor, then connect the other side of the resistor to the Vref wire (5 Volts).

In the first statement, the "Vref" says only to connects it to the MAP sensor and the TPS sensor.
I have finished my wiring and it would be a pain to get a wire back to the Microsquirt for the Vref. I have a SSI-4 from Innovate that can supply 5Volts, can I use that instead?

65looter,

Yes, you can use another power supply for the LEDs. The MegaSquirt wire grounds the LED, so you could even use a 12V supply - i.e., the battery (with a higher resistance resistor - around 1K Ohms).

I will clarify the manual right now.
