hello, the prices include the engine cover. yes we can make the hole larger
the one on mine is smaller because of the hook on the end. i did this to match the strip on my car
. the outer lights are not part of the set up. i have them on my car
but these run off a separate remote box that also controls my dual halo and DRL's
. wiring is very basic, power wire to the fuse box bolt and the other to any ground
thank you
