202U wiring diagram for garage door opener

I trying to replace the old receiver for my garage door opener and want to verify the wiring connections. The wiring diagram for the opener is attached here. Do you have a wiring diagram available? I also need to know if the 202U v6 is a 2 or 3 wire unit. Thanks

See below

There are 2 wall switches that are working fine. The garage door opener has 3 terminals; common, relay and 24V. If I want to use the #2 relay, what terminal on the 202U should the garage door opener be attached to.

It should be #2’s NO & COM.
