Double Coil Triumph 100 Efi Year 2012

Hi in UK.
On the coil part no T 1290101 which one of the connection is +..?
My coil is not marked with + or -... does it matter?
There is a Green-silver cable coming from terminal B 17 and another
Brown-Pink from terminal A 6.
My coil is round side down and the spark plug cable going backwards.
The Spade Connections (not marked) at the front of the bike.
