HEY DEATHRAT, WHAT IS THE MSD BUICK INTERFACE AND WHAT DOES DO? :o

As far as I know.. what it does is to allow a quick bolt-on and forget.. it has all the wiring harness spliced and re-routed for you, so all you have to do is install the unit.. plug in the adapter on one side.. and to your normal plug on the other...

I guess that brings me to my next question, how difficult is it to install the DIS 4 in the first place ? Would you need to splice into wires and such without the msd interface? I already found a location for the unit. I bought a k&n cone filter which freed up the spot where my old air box was.

As stated by Drifter it'* like "Plug-N-Play"

You'll have to ask the Demi-god A.K.A. Deathrat about the wiring and which ones would need to be spliced and all. Personally.. get the adapter.. worse case scenario.. you can extend the wire between connectors, and that'* more straight forward..

COOL THANKS FOR ALL THE INFO GUYS. I THINK IT WILL MAKE LIFE EASIER ON ME TO GET THE MSD BUICK INTERFACE.FEEL FREE TO ADD ANY ADDITIONAL INFO ON THIS TOPIC.
