I need a 12v output to control my fuel pump relay. I have microRusEFI v0.5.4. I found JP2 for switching high side level from 5v to 12v. What else needs to be done?

You should be good for low current relay control, not direct pump control.

Yes, it is working now. So JP2 setting affects all GP outputs 1 thru 6? Ignition outputs are always 5v regardless, correct?

I believe that JP2 only affects two outputs

yep, exactly like https://rusefi.com/docs/pinouts/microrusefi/ spells it out

Thanks for that pinout diagram, in all my searching I never saw that, I've been going by the one on github which doesn't say anything about which pins are high low or push-pull.

rusefi.com points at https://github.com/rusefi/rusefi/wiki/microRusEFI-Manual

Just added link directly to https://github.com/rusefi/rusefi/wiki/microRusEFI-Manual

Previously one had to click https://github.com/rusefi/rusefi/wiki/Hardware-microRusEFI-wiring to see pinout link

This is the pinout I have been using https://github.com/rusefi/rusefi/wiki/Hardware-microRusEFI-wiring
The problem is that it doesn't name the output types. It describes the different types of outputs, and says which pins are outputs, but it doesn't say which pin is what type (gp_low vs gp_high), they are all just called GP. It's not wrong, it's just incomplete.

Just changed it a bit https://github.com/rusefi/rusefi/wiki/Hardware-microRusEFI-wiring
