Shipping is additional but shouldn't be much as it is light.

So is this thing plug n' play or do you have to splice it in? The instruction manual isn't clear.

 

You can either order a T-harness for the ignition lines, or splice them in. The other lines need to be tapped into seperately. It is not plug-n-play but is not difficult to hook up either.
