Presently I have a Hunter SRC. Wiring picture attached and I am considering to purchase a Rachio 3 . Do I have just to copy the wiring ? Thanks
Yep! Only two wires you won’t need are the 2 yellow, since that comes from the power supply of the Hunter (that 3 bundle wire can be tossed with the controller). Otherwise, it should be an easy plug and play since you have no master valve or pump.

I double checked what @tmcgahey said with the manual at https://www.hunterindustries.com/sites/default/files/om_src_em.pdf
As he said, you will not use the two yellow power wires. I would disconnect the transformer on the other end and use the supplied Rachio power. Then, everything goes straight across C->C, 1->1, …, 9->9.
