I am replacing my failed NavWorx ADS-B with UAvonicx Echo. Which wire in the NavWorx connector is the GPS input fron my GNS 430?

Also, how many wires do I need to connect from my GTX 327? The person I talked to said pin 20 connects with pin 1. do I need a altitude input at pin 3.

Thanks for your help.
