Can anyone tell me if a 69 Spider had optional hazard warning lights? I have the wiring diagram, but there are no hazard light components in it. The car has them (toggle switch is mounted under the air control levers on the bottom center of the dash) and it appears to be original. I'm looking for a wiring diagram of that system.
Thanks, Greg

euroah: I think your next task will be to see if your car has components #22 and 23 in that diagram; the e-flasher unit and light relay. I'm not sure replacements for those two parts are available, other than used parts which may be scarce.

It sounds like your car does have component #36 - the switch - but I'm guessing that the e-flashers don't come on when you flip that switch. Does that switch - and its wiring - look original? Or might a PO have wired a fog light or ??? to a switch in that location? If it does look original, you may be able to trace the wires back to components #22 and 23. Sorry, I don't own a '69 roundtail, so can't tell you where Alfa mounted them (anyone know?).

You are unlikely to be able to find a replacement for the flasher (#22) if it isn’t working. Many years ago I was able to replace its function with a standard flasher and a light bulb. Not original but it works. I’d have to crawl under the dash to describe more exactly
where #22 and #23 are located and to remember how I jury-rigged my car some 30 years ago.

That looks to be a standard signal flasher not a substitute for #22 in the 69 USA emergency flasher circuit.

Greg, does your car have anything mounted on the firewall near the brake fluid reservoir? There should be a Bosh relay and a Bosch flasher unit there. Those are the two items that are needed for the 4-way flasher system to work.

The relay is on the left. I believe that is Bosch 0 332 200 009. The flasher unit is on the right. That is Bosch 0 336 850 002. Finding an original flasher unit is going to be a bit of a challenge. The relay should be easier to find.

If you want something that works and don't much care about originality, one of our members figured out a solution a number of years ago.

My apologies , the fix I put together almost 40 years ago was for replacing the flasher #23 not the relay #22. My relay and flasher were originally in the place on the fire wall as in Ossodiseppia’s photo in post#10. I remember that part as a large rectangular box (mine was one of the later 69s made) but it has been a long time.
