Emergency hazard switch - testing and fitting

[Merc_Girl]

Hi folks

Me again!?!?

So, I’ve recently purchased a period (I have an early Pagoda), what I would name as a ‘hazard warning switch’.
Slight flaw in my plan is that I don’t know how if it works or indeed how to wire it in, so only minor problems!?!?!?

So, to summarise, I’m calling out to all electrical pagoda gurus out there to :
a) advise how I can test to see if the system still works
b) how can I hard wire it in? (I’ve looked on the wiring diagram in the technical manual but couldn’t see a reference to hazard warning switch

As always, any advice greatly welcomed 🥰

Hi Katie,
your new hazard switch should have following terminals:
New                                                                                                Old
15:   + ignition switch                                                                      (15 - black/red/green)
30:   + battery                                                                                 (30 - red/blue/white)*
31:   - battery/ground                                                                     (31 - brown)
49a: flasher (exit, clocked)                                                              (54 - black/white/green)
R:     flashing light right                                                                    (R - black/green)*
L:     flashing light left                                                                       (L - black/white)*
The new switch/relay replaces the old flasher relay (wire colours may vary).
* flasher plug
BUT: Differences such as 230-250-280, US - Europe, manual transmission - automatic transmission, etc. can lead to differences in circuit diagrams, pin assignments and cable colours.

Katie, please post a picture with pin connectors numbers.

Hi, Katie,

I, too, have a 230SL and have purchased one of these switches.  I've studied the wiring diagram and understand how they connect to the existing wiring.  However, building the wiring harness with the correct plugs is somewhat challenging, including sourcing the connectors.

I believe that our member Leonardo Peterssen (lpeterssen) has offered to make them (for a price, of course).  Just another option...
