Hi All
Firstly happy new year to every one, and now for the help. I have purchased a hall effect sensor from Burton power to fit my type 9 gear box . it is has 3 wires

Brown/Black
Brown
Brown/Yellow
I believe the sensor is from a Ford Transit/Focus I can not confirm this a the part number has been ground away . I take it that brown is negative and the other two are signal and power can anyone tell me how to test or point me in the right direction for a wiring diagram that has correct colour codes I have googled it but have had no success many thanks.

When I did mine.


Black is switched 12v 
Brown is earth 
Yellow is signal out to your gauge

THANKS TO YOU BOTH. Gremlin I was looking on the on-line catalogue and not the website (note to self must try harder) at least I can get this fixed before M.O.T thanks again .
