Can anyone make sense of where these wires need to go?

I have a pre-made loom and i have 7 wires in the hazard wiring circuit.

The first 3 I presume are for the indicator switch as there are no other wires present for the indicators.

green/white, o/s indicator
green/red, n/s indicator
green/brown, flasher power feed, flasher relay pin 49a

then I have 4 left

green/pink, hazard feed flasher relay pin 49
purple, perm live
green, switch live
black, earth

What would be the best way to wire this up?

The hazard switch I have has 5 terminals. 2 are for the led and the other 3 work like this. Switch in off position, 1 & 3 continuity nothing to 2. switch on and continuity from 1 to 2 and none to 3 if that makes sense.

Will this switch work or am I better of buying a different one?

I don't think that switch (alone) has enough terminals.
however, the wiring colours you have are the good old BS wiring colours, so look at original mini, triumph, land rover etc for a switch.

After looking at wiring diagrams I have binned the switch and just ordered a savage switch with 6 terminals.

hopefully this will make it easier to wire up.
