Vespa

Hi all I've acquired a vespa et4 most jobs completed but I'm a bit stuck
Each brake lever has a cable coming from them but dont know what they plug into any help plz

 

brake light switches?

 

Not sure thought is was something to do with the starting of it
i.e depressing a brake lever before starting it ? But I'm not sure

 

Yes, pull the brake in, brake light comes on, allows you to start the bike

 

Yes that's it need to know what these wires plug into ?

 

So it's not brake light switch after all so I'm still at a dead end as to where these wires plug into cant upload pictures wires are attached to the grips any help please

 

The only wires that come out of grips themselves are for heated ones

 

photos would really help

 

Ok if that's the case got nothing to worry about for some reason cant upload pics thankyou for your help
