Kevin, although you haven't asked I wonder if you are aware there should be existing wiring already in the main loom to accommodate auxiliary front lighting. Look for redundant blue/yellow wires under each front wing. Under the offside you may find two such wires, the second with the help of a double female bullet connector (which may already be present) loops the same feed from dash to the nearside. Each lamp will require it's own ground connection as well. Again there may be some redundant black wires under wings to provide these.
The other end of blue/yellow wire will be tucked away behind the dash although later variants after 2007 had the wire terminating in a multiway connector. As this redundant loom wiring was provided for optional front fog lamps you will need to add a relay triggered from the main beam blue/white wire (suggest intercepting this light switch cable at main loom) as well as an extra switch such that when selected to be on they will only do so when main beam on headlamps is selected. You will also need an extra fused main power feed to pin 30 on the relay although current required will be minimal given you are using LED type. If you require more detailed info on fitting the relay please PM me.
