HPD Wiring Install Questions

I have a few questions regarding the installation of the Fit chassis loom.

First, regarding the fuel pump out lead - I assume that the lead goes through a momentary switch to ground. Is that correct?

Second, the ECU Diagnostic LED - assume that goes through the LED (maintaining proper polarity) to ground?

Lastly, we are using an external fuel pump. Can I replace the loom connector with terminals?

Thanks in advance,
