1973 Dodge Coronet Hazard lights relay location?

[fullmetaljacket]

Where underneath the dash on a '73 Dodge Coronet would the hazard light relay be located?

On my 74 satellite. One is above the brake pedal and the other is at the ashtray. I can’t remember which is which.

Gotcha. Thank you. It's quite tight under there on those cars.

On the 1973 Coronet:

• The turn signal flasher is mounted to the outer side of the ash tray.
• The hazard warning flasher is mounted on the brake pedal bracket.

Great. Thank you fellas.
Everything under there is original Chrysler.

Tipically and if still from factory, hazzard (heavy duty units) uses to be square while turnings are the traditional round ones. I think it was just about manufacturers…

Mine is a square unit. I took it off the fuse box and all of a sudden, the Door ajar/ headlights on/key in ignition buzzers in the car didn't work. When I plugged it back in, the buzzers worked. Could it be that the hazard lights and the buzzer are in the same unit. My square unit has four connect prongs.

The pictured item is the combination horn relay and key-in buzzer.

The horn relay/buzzer can be seen in the following excerpt from the wiring diagram:

The 1973 Dodge Chassis and Body 2-volume set, which covers the Coronet, is available for download at My Mopar: Service Manuals.

Correct.
The three grouped prongs are horn relay section, while the one appart is the buzzer section. That’s for 71/73 Mopars. On 74 it became in only Horn relay while the buzzer was moved (prong disappeared) to a diff buzzer and controlled by the interlock box.

Both hazzard and turning signals flashers use same prongs and same disposition. In fact they could interchange HOWEVER using a turning unit into a hazzard will overheat faster and could fail sooner. The hazzard units are designed to handle 4-6 bulbs, while turnings 2-3 bulbs. You can get a diff speed blinking too.
