[T3] Emergency Flasher Wiring

In my recent trip into my wiring I have partly solved an issue with
the E-flasher. Wired the way the diagram shows with the switch across
the relay's S and 49a the relay would just buzz when the flasher
switch was closed.

I'm using this diagram:

The relay I have has the 54 and 54f terminals, not shown on the
diagram. I found that connecting one side of the switch to 54 resulted
in a working hazard function.

This is the relay:

My problem now is that the hazard lights only work with the key on. Not ideal.

Any suggestions?

The only other change I've made is to move the horn to switch power.
