Well, a quick update......

Got the wiring checked out and used a decent meter to find that the wire to the hazard flasher was intact to the fuse box. Retested and found 12V on the Blue/white wire at the flasher unit. I have another hazard switch so was going to try that.......AS I was pulling and messing with the wires on the back of the hazard switch, I tried the hazards again, and it all worked....... hate that. Must be a bad connection or wire issue so I am assuming the switch is bad. But the switch I have has longer pigtails and different emblem on the toggle switch than the one in the car, so either need to rebuild the existing switch or get another one........

I guess I will replace my accessory relay too, since mine looks bad. Might as well replace the flasher unit for the hazards. I did see that there is different part numbers for the turn signal flasher and the hazard flasher...... Need to figure that one out.

Getting closer to the answers, thanks for all that have responded

I found on my car, vin is about 14,000 early car, the car had a hazard switch with the short harness. The longer harness one I had messed everything up. I don't believe they are interchangeable

@WJ4Fun When I did the LED conversion on all my lights I used the same flasher for both blinker and hazard lights and both work just fine. No idea why Nissan would have different part #'s for the flashers.

Ditto.

thanks for the feedback,
Any suggestions in getting to the back of the switch and removing it? It seems like taking the tach out would get you close? Anyone have a good short tail hazard switch around?

I wasn't there when they designed it, but my assumption would be the difference in the load that the two flasher units see. The turn signals are flashing four filaments (three in the rear and one in the front). While the flashers are seeing twice that (six in the rear and two in the front).

The "off time" portion of the flasher unit is predominantly controlled by the load attached to the flasher unit.
If that load is too small (like using LEDs), the off-time will be.... forever.
If that load is too large, the off-time will be too short and the on-time will also longer than intended.

The point is... The flasher needs to be matched accordingly to the load it is being used to control.

I thought I had pics of both flasher units (turn signal and hazards), but I can't find them.

Memory says there are markings on the outsides of the cans that indicate how many filaments each one is designed for.
