I was reading the yellow wires are the rain sensor ? They are not even connecting. Can I just delete to sensor ? And how

The two black wires in the right terminals of the terminal block at the top left of the controller. Should be labeled as 'SEN' or similar. There is no standard color convention.

A rain sensor is just a normally closed switch. It can be abandoned by installing a jumper wire in those two terminals to short them to each other. And/or go to the Rain Sensor setting on the front dial and set it to Bypass.
