its all plug n' play. It does come with a resistor but does not require any splicing.
In the image you can see the harness with the resistor. You simply take the original power socket and plug it into that lonely socket (displayed in the image) and your ready to go. Find a place to mount the resistor, tuck the wires away and your set.
