Identify Connectors and Supplier

Hi,

I am trying to identify a connector used on a chassis harness to the ignition switch on a Westfield SEiW. I have attached some pictures. This connector can have up to 5 terminals installed, another used in the hardness has 7 terminals. I did find on the inside of the larger plug the letters AMP. I have search the AMP (TE) website but still unable to identify. Thanks in advance for any help.
