Should I splice them into my headlight set-up?

In this way the fog lights as well as the aux lights stay on only with lowbeam(spliced to the yellow wire).

If you want them to work with high beam, splice (6) to the highbeam wire (on my 2003FXD it's the white wire).


If I understand well, you want them to work independently from high/low beam.
To achieve this result, splice (6) to the runing lights wire (see your manual for the color, on my 2003FXD it's the blue wire) or run the "unterminated wire" (6) (= wire to low beam in Fog Lamp Schematic) in the wiring harness back to the + on the battery or the aux fuse in the fuse box.

You can operate the switch (which comes with the kit) to activate the coil in the relay which will turn on or off the fog lights/aux lights.

I have connected the passing lights on my FXD2003 in the same way and replaced the stock switch from the kit for the handlebar mounted aux switch kit and the chrome switch cap kit.
