eBay - go to "RC and Control Line" and search Ice charger, more than one pops up. They don't seem to offer instructions with the parts. Maybe you can find a how-to on the 'net somewhere.

BTW, they mean professional install recommended, its not an install for someone that doesn't have the needed skill level. It will ruin your charger if you mess it up and a big tip - DTX doesn't sell the part that gets ruined (screen). Seen lots looking for new screen - basically you almost buy new charger when you send it in for repair.

Yes, I've done several, years ago, mine and several for friends. Sell your Ice and buy a TC1030 charger - its backlighted, but otherwise basically the same charger.
