In general wiring doesn't just go bad.

Most issues are with the ends of the wire, which are easy to replace.

A method I've used allot is to leave wire in place but cut it off and terminate it at a terminal strip on both ends. Then you can wire from the terminal strip to the devices on each end.

If you really want to replace the wire, you can also use multi strand wire. I've used wire with as many as sixteen 12 awg conductors. Its pretty common stuff in the instrumentation world. You really do not need that many conductors for an engine. 8-10 wires will generally be enough for an engine instrument package depending on how you wire it.
