Tom,
There is a 2nd relay if you have a switch for hazard flashers.
2nd relay must also be changed out and polarity tested.
Will cause no flash issues if not changed out.
2nd relay likely mounted conspicuously on/near the fuse block.
If that's not the culprit then I'm not sure what it is.

Put your hazard flashers on and listen for where the telltale 'tick-tock' sound
the original relay makes when it's flashing your lights on/off.
That sound will lead you to the relay location.

As a final note, when you complete the change over to all LEDs, those
new solid-state LED compatible relays will likely lack the 'tick-tock' sound.
You'll have only dashboard light cues for turn signal and hazard flashers.
With Cobra side-pipes you can't hear it anyway so no loss. HA!
