search button works wonders. there is lots of threads on here and all over google about this. I believe atomicmods even has a step by step tutorial.

but for a quick and dirty answer...

on your evo board the 2 biggest red and black wires you desolder, and attach half of the harness plug that the pack will come with.

then you remove the battery tray. and attach the lithiums. plug in the 2 connections and go. Pretty straight forward and simple.


edit* here i even went and found you the tutorial.
