config tool question

I'm using the RRF config tool to make a new config file but I'm having a hard time understanding what to put for the I/O mapping page. specifically in the endstop pin for the Z axis since I'm using a bl touch as my z probe. also, in the area where it says modulation pin under the probe section. it's a bit of a mystery to me. As for the wiring, I'm using pin 1 for 5v, pin 2 for gnd, and pin 8 (heater 3 I think) for pwm, and the probe in for the black and white wires from the BL touch. Pretty standard set up from the documentation I could find online. I'm attaching a picture of the portion of the page I'm not sure about what to put in those boxes.
I'm not even sure I need to fill them out since I know there is a later page that will ask about endstops and probe and all that.
In the endstop dropdown for the Z axis, choose nothing. You'll define the Z probe in the endstops page.
In the Z-Probe section you would choose zprobe.in as the input pin for the bltouch that takes the trigger signal. And the PWM control pin that you want to use for servo control to raise and lower the pin. Usually Heater3 on the expansion header. As you've described.
Then on the endstops page you choose bltouch as the probe and probe for the z axis.
Probe configuration is a bit disorganized in the current version of the tool. It really should have it's own tab with all of the relevant settings there I think. It's complicated though because there are many different kinds of probes that require very different ways of wiring and configuration.
