Waveshare 2.9in epaper pinout to WiFi Kit 32 v3

Looking for some help in pinning out a Waveshare_2_9 to a Heltec WiFi Kit 32 v3.

This is what I’m trying to match up:

Can’t seem to find DIN and some others.

My Pin-Setup is:
GND -> GND
3.3 -> VCC 3v
DIN ->
CLK ->
DC ->
CS ->
RST -> RST
BUSY ->

Thanks for any help.
