R34 Hazard Switch Wiring Help

[HLSkyliner34]

Hey,

I was wondering if anyone could help with a photo or diagram or advice on how to wire the 8 pin hazard switch into an R34 GTT?

We're currently replacing the R33 hazard switch that was in the car when we brought her last month. However, we are having trouble working out what the pin config is on the R34 switch (i.e. what pin connects to where) and how this correlates to the current R33 connections?

Thanks in advance for any help 🙂

The wiring diagrams are in the workshop manuals.

Sadly, I don't have the R34 wiring diagram handy, but....given how little different most of the 3/4 are, I wouldn't expect there to be any difference in the hazzard switch.

Awesome thank you for providing us with the R33 diagrams they are a lot clearer than the drawings we were working too! 🙂
The biggest difference we're finding is the R33 connector we've just removed has 2 rows of 4 pins but our R34 connector has 1 row of 5 pins and 1 row of 3 pins (1 on the left, a gap in the middle and then 2 on the right) 🥺

Yuh, she's pretty simple when you study it for a few minutes.

When the hazard switch is off, the power to the indicators is fed from one fuse, across the first 2 terminals to make power available to the flasher unit, and that then gets sent to either the left or the right lights according to the flasher switch position.

When the hazard switch is on, the power from the indicator feed is replaced by the dedicated feed from the next terminal down, gets sent out to the flasher unit, then comes back into the hazard switch where it gets forwarded on to both the left and right lights. You can tell what terminal is what by checking for what contacts change between switching on and off. The three that are common when on are the light feeders. The three that swap inlets with a common outlet are the power supplies. The other terminals are for the local (night) light, one of which is earth and the other is fed from the parker position on the headlight switch. These could be reversed without problem, assuming it's a globe and not an LED.
