diac to triac connect

How can I connect the diac to the triac?

sorry to tell you that two diodes connected back to back is not diac, as the operation of diac is to conduct/connect when the voltage across it exceeds certain value 24v or 12v or whatever voltage.

use a voltage measurement with one terminal connected to the diac section and the other to the ground node, and feed this measured voltage to both the gate terminals of the triac
