Upgrading from Anet board with Auto leveling

To the 5v on the right.

Where would I plug in my sensor? The E0 stop, z stop or zprobe?

FYI I just ordered the duet wifi!!

The outer 2 pins of the E0 endstop would be best.

Thanks! I'm sure I'll have more questions once my board arrives!

Ok so I just received my duet wifi!! I have setup the wifi and am able to access the web interface. I was going through the RepRapFirmware Configuration Tool and had some questions on translating my marlin settings.
I have provided links below that shows comparisons between marlin and the config tool.

I think I have everything setup. the only thing I'm having issues with is the zprobe.
I have the zprobe wired up as dc42 suggested.
the gnd and signal pins from my sensor are wired to E0 endstop connections E0 stop and GND.
I have the 5v for my sensor connected to the 5V expansion connector pin 1.
when trying to run G29 I keep getting this error

Error: No valid grid defined for G29 bed probing

Below are some of my config settings for the z probe and my bed.g file

thanks for all of the help.

I think i found my problem. Let me know if I'm right.

When setting up the grid with M557 I should subtract the z probe y offset (53) from my current numbers.
I believe it should look like this: M557 X10:210 Y0:157 S40

You don't need to subtract the Z probe offset, however any points that are not reachable by the Z probe will not be probed.

My guess is that you had a typo in your M557 command.

Thanks for the help. I have everything working now!
just as a reference below are my zprobe and bed.g configs

You don't need the M374 command, the G29 S0 command will save to heightmap.csv anyway.
