Temp sender question

I'm going to put an aux temp gauge into my little brothers Surf (LN61)for him.
I'm assuming that one of these senders is for the factory gauge?...but when I removed both plugs the temp gauge stayed smack bang in the middle! Another design 'feature' maybe??
Seriously tho, why does it have 2 temp senders?
And does it matter if I remove one to fit the new gauges sender?....Which one should I remove?

"B" has a yellow wire that disappears down behind the injection pump.
"A" has a green wire that goes to here...

earth out both wires, whichever one has an effect on the temp gauage is the one you want, make sure the ignition is on btw :P. if this fauls I'm pretty sure its the yellow one ;)
