Might be able to help hear.

As you look at the terminal block (the wires away from you) they should be


Left - High Beam + (blue)

top/middle - Low beam + (yellow)

right - Earth - (brown)


If you had the previous bulbs with 3 pins (non halogen) you need to swap the low and earth over.


At least that was what my Land Rover required to get them working correctly.

But cannot guarantee colours as it had be mucked about a bit.
