I have a push-pull Hella switch with three spade connectors on the reverse. I would like to fit hazard flashers to my 1971 van and wonder if anyone has done so and could supply a wiring diagram. I know various kits are available but I wondered if I could use the Hella switch.
Thanks
Tom

Re: Hazard flashers
I spent ages trying to figure out how to wire up a modern Savage switch for hazards and in the end gave up. I'm sure it would be possible to use the Hella switch but it will probably involve a new flasher unit and it may involve adding diodes to prevent current feeding back unintentionally. The Morris flasher is rated 2x 21w + 5w for the telltale light, you need to have a flasher rated at 4x21w +5w to run hazards.
Holden have some very handy wiring diagrams on their site but I struggled to figure how to make a modern switch work with the Morris wiring. Just scroll down the page to find appropriate circuit.

In the end I used the kit available from various places at vastly differing prices and of differing quality switch, this is very simple to install. Example below. This has 6 connections.

Sorry I didn't answer your question but in the end I gave up as it wasn't a simple process.

Re: Hazard flashers
Search for posts with Hazard as we've covered this in some detail before. In a nutshell you won;r do it with just that switch; and the simplest thing is to buy a kit, readily available. It might go against the grain, but in the long run the kit will be cheaper, neaster and more reliable than any home made concoction.

Re: Hazard flashers
As Simitc says you wont do it with that switch, most kit switches have 5 terminals. You could use an MGB switch and diagram but you would end up with a large rocker switch that would not suit a Minor and those switches can be troublesome.
