Wiring to indicators and trafficator works from the same column switch

[Tk41774]

As title. My brain is hurting trying to wrap it around this

I have a 1958 2 door that is currently wired for just indicators. It does have trafficators however the wiring for these is missing.

What i am trying to achieve is when I turn on the indicators either side they flash and the trafficator will operate at the same time. I have tested the trafficators and they're operational so it should be achievable

Where my brain if failing me is how to wire it to do that, my best theory so far is to use 2 flasher relays after the indicator stalk with a couple of relays, but does anyone have an actual diagram to achieve this

It is converted to negative earth if that helps

Hi

There a few issues to deal with here, so I'll write them here in the order they come to me, not necessarily in the order of 'severity of issue'.

Don't worry about the polarity, it's not relevant (apart from ensuring that any LED lamps you might use are the correct polarity).

The first thing is how the Indicators have been installed to your Trafficator Car?
Does it follow the concept of the Factory fit, where the circuit goes 1- Supply, 2- Flasher Unit, 3- L/R Selector Switch ?

As you have surmised, the simplest thing to do is change it to be:
1- Supply, 2- L/R Selector 3a- Feed to relevant L/R Trafficator and simultaneously to 3b- Feed to Relevant Indicator Flasher then to Indicator.

Essentially as the diagram that MM1949 has posted for you, while I was writing this.
