This is the wiring diagram for my 2013 Toyota Prius Plug-In Dual Switch DRL and LED Light Bar, using this method the DRL’s are controlled by a switch.
I started out drawing the diagram up on my tablet, it was easier to let the creativity flow.
Since this is a dual switch, you will need one relay per switch. So yes… that means you need two relays, there is a link below for which relays you’ll need.

Now for what you came here for… the wiring diagram! Let me know if you have any questions by using the Contact Me page.
Interesting fact, I re-wired my last vehicles DRL as well…
