Thanks very much fellas!!!
All sorted!
The purchased buzzer 1. WAS FAULTY( would you believe it?
) It was by accident that I tapped it to get a little buz.
And yes my left door switch was the wrong one. IT SHOULD HAVE BEEN A 3 PIN SWITCH.
I remember the courtesy light would not come on (unless it pulled the toggle out slightly (must have been sticky) and purchased another switch (2 prong) and made it work by cutting the 3rd prong to get it to fit.
26 months later - It came back to haunt me as I wanted to get the buzzer in.
In the meantime I am trying to get a refund of "this so called NOS FAULTY BUZZER) and ended up installing a small electronic buzzer to that lead to get things going in the meantime
.
Being in Australia (I could not be bothered waiting for this part to come (ebay first shipment went missing and he sent the 2nd buzzer which ended up being faulty in the end).
.
I thank you all for your help and Hope this info will save someone down the track!
I must admit - I am loving the buzzer sound - Just because it was back in the day... perhaps over time it will annoy me but I think no (with a smile
Thanks again!
