Help for newb
 

I just got a 99 dodge 2500. I never owned a dodge truck before I do have a 2012 duramax. Anyhoo my dodge has a diablo power puck under the hood. I was wondering if there was certain steps to take it off or just unplug it and done done ? Was wanting to use an actual tuner on it in the near future so figured I need to remove the power puck first.

Just trace all the wires and disconnect. Reconnect the factory connections and you should be good to go.
