Dave, generally Cat5 and automotive cable is insulated with PVC. PVC is flammable, burns readily creating copious amounts of thick, toxic smoke rendering it virtually impossible for pilots to see their flight instruments or BREATHE.
I would strongly suggest you use aircraft quality wire (Tefzel) or research other types carefully.
