roughly you are gonna need, smarttrax 3d node, smarttrax mdu, and mounting kits for both. wiring harness for the mdu, wiring harness for the node, can tee, and depending on the wiring harness that is already in the nitro, might need a cab kit for it too. 

used mdu's are kinda rare, beings they were only introduced about four years ago.

depending on a couple things I might have one for sale all ready to go.
