<!-- from fixya rte -->2010 tacoma wiring diagram - 2010 Toyota Tacoma

The flasher relay is working for the turn signals so less likely it's the problem but needs to be tested. I'd start with the ground for the hazard switch (right kick panel) and the hazard switch.

Verify the hazard input to the relay is shunting to battery negative via the hazard switch. See attached wiring diagram, no tow package. Some wire color codes are different with the tow package but logic is same.

if it were me and i'm not a pro.. remove the driver side door panel and i would waste a little more wire and wire it straight into the power door lock on the drivers side that way you should avoid and computer issues as you know you are wired in behind the relays again I'm not a pro i'm just a weekend shade tree guy

Question edited for clarity.
Question moved to model category.

Free wiring diagrams are normally only available to small sections. for a full wiring diagram, you need to buy a service manual.
