Series III, Station Wagon, Hazard Switch/Lights

Hello fine People from LZ !

I am restorating a SIII, Station Wagon 109, 2.6 Petrol (1976). I put out all the wiring and put in a loom from british wiring. Things like heater, windscreen wipers/washer, horn, etc etc function quite well ! The only thing i cannot get running are the hazard lights/switch. Indicators are good and function well !
British Wiring send me the instructions from Autosparks, but that doesn´t work and its also a little bit confusing.


Maybe my wiring is faulty? I have numbered the wires, maybe somebody can help me !

1) Brown - goes to hazard warning relay
2) light green pink - goes to hazard warning relay
3) green - with male spade should connect to ->
4) green??
5) yellow green - to flasher relay
6) red green - from the steering switch? (also flasher relay??)
7) black - earth
8) brown - fusebox

4 and 6 are keeping me frustrated. I don´t know which green wiring i should take to connect it with the male spade?? In my fusebox are a lots of green wires.

My indicators a working fine, but when i pull the hazard switch, indicators aren´t working, when i put the hazard switch back, normal indicators work fine. I tested it with an old and a new hazard warning switch (both lucas)

what type of hazard switch are you using (images please Hella etc )

Hello. I have 2 Lucas pull switches. One is new and the old one.

any images of your hazard switch connections and wiring

as the indicators work ok the ignition fed side of the hazard switch is working .where the brown fed from as this should have a battery feed for the hazard switch to work when pulled out,try taking a fused piece of cable from a known battery feed to the brown on the flasher relay and try hazards ,if this works the brown feeding the hazard switch requires looking at

Thank you. I will give it a try tomorrow after work.

I’m doing the same, which pins on each relay do you have the coloured connections on?
The green that comes with the switch should be connected to the green you pull off the normal flasher relay.
I’ve got some RDX relays with 4 pins +, -, L and L1/ I.
I’ve attached a couple of photos. Don’t have the relays on bases yet but you’ll see that on the haz relay, brown goes to +, - to earth ( not yet hooked up) green/pink to L. And on flasher relay, Green/yellow to + and green brown on L. The L1/I connection is for trailer warning light if you have it. It’s load sensing and you can adjust the relay so that the trailer light goes out when indicators on and no trailer hooked up.
Now, the caveat is, I haven’t powered mine up yet as I am in the middle of it all. Hope this helps and that someone else can verify it for you.
