Brake Light Switch - 2, 3 or 4 pin?

[forza]

I have a polo Mk3 1999 1.4 and need to replace the brake light switch. Before I buy the part, GSF have 2, 3 or 4 pin brake light switches.

Can anyone confirm to me what one I should be using without having to go under the dash to take it out and look.

Thanks in advance,
Alex

dunno cos your car is a 6n commonly known over here as a mk4, whereas everywhere else calls them a mk3! try asking in the mk4 section!
