So I started playing RAGE, and I'm pretty sure I found a point early on in which it's impossible to continue the campaign. I had just acquired the lock grinder schematic and necessary components. There are two locked doors at this point in the game, one in the ghost hideout during the first mission, and another in the dam. I wend to the optional locked room in the ghost hideout first, and now I can't find another electrical wire kit needed to make a 2nd lock grinder to progress the campaign. I looked everywhere (shops, sewers, etc...) and can't find the missing component. Any hints/solutions that don't involve cheating?

Though I may just do that as a last resort. But seriously, i would like to know if there's a 2nd electrical wire kit available at this point in the game.
