?? Behind the gauge cluster

[lookingtobuy]

Hi all

I was doing some bulb replacement on the gauges and was wondering if anyone could answer 2 questions.

1. One of the sockets is white with a male spade terminal, it is the bulb that lights one side of the speedo, any idea why its different??

2. There is a wire with a female spade end all wrapped up in the column harness, again any idea as to what its for??

Thanks and have a great night----
