I was just going to cover that...in this instance your best friend is a small candle, a heat gun , and or a soldering iron...remember heat is your friend and yer dealing with plastic so warping it or even burning it through then heating the edges and bending them inwards makes for an awesome effect...(I have a few 32nd scale WWII dioramas with this kind of damage...)
WARNING>>> go slow and experiment on odd bits first...don't wanna ruin the final cut so to speak...as for wires for the inside...heat up a bit of sprue and start stretching...also makes for wonderful antennea cables and other thin stringy items...and remember to watch you don't burn up what yer workin on...a little heat goes a long way and the plastic will stay warm for a few seconds...
