So right now as the system stands it goes that you need to carry 3 or 4 wire parts around with you to do most any kind of repair just in case. Now while this is all good and dandy ( limiting inventory is a nice way to force people to specialize ) it could be fixed, if you wanted it to by have the wires have a bit of tweaked properties.

First : Have wires have a set distance for them but either a high limit to how many times they can connect or unlimited connections in that distance. So basically you remove having to have a shitload of wires for making a door work again since you have to have at least 2 just to make some very small connections. This option comes with a downside in that if you remove 1 segment you remove all of them, or on the other hand if it splits them you then have unlimited wire spawns which is not so great.

Second : Have a new item in the game called the spool of wire where its a spool containing exactly what is described above (wires with a certain distance but lots of connections) that has about 10 or so. Maybe just the little wire segments inside and can be used as a normal wire multiple times. This option would be a bit easier to work with since you can easily identify who's been wiring shit since this item would be a dead give away. Also from a technical point it would be easier to code since you could set a value to the spool and have it work exactly the same as the normal wiring but have it have multiple uses.

Hopefully these help I've been messing around with the wiring and its a great feature. Would love to see it expanded upon.
