led 19 + good internal source of 5v?

Post by turbothis »

i wired in the table switching and used the positive leg of led 19 for the 5v external switch
any better place to take the 5v from the inside of the board?
i dont use it for a spark output (running edis 6)
seems to be working fine but would like some pro tip or something....

The 'positive legs' of those LEDS is via a current limiting resistor. For 5v from that area, you need to pick it up from the other side of D17's resistor - R23. Or from the 5v feed to your TPS in your wiring harness.
