Wiring led to the secondary fuel pump
Hello,
can anyone please show me a diagram and what I would need to install a led as a trigger failsafe when the second pump turns on with the Hobbs switch??
Thanks

you need a 12v led. Tab the power source on hobbs to the led, ground the led. Mine was setup like that(IIRC). This LED won't tell you if the pump is working, it will tell you if the hobbs/relay are working. If you're using the stock ECU and Tephra V7, you can wire in the o2 and have a AFR/lean safety in conjunction with the led.

I'm using a AEM v2, yes I wanted a safety on the hobbs as it can fail or stop wotking.
