i have the most basic set of dials which has the fuel gauge speedo and a clock!

i've sourced a unit that has a temp and rev gauge, but im wondering if many people know whether all the "extra's" are wired up and i have to simply "plug&play" or if i have to wire everything up from scratch.

i know not very much about fiats, but i ask because a mates corsa didnt have front fogs so when i went to fit them i went all guns blazing expenting wiring to come out my ears when it was already there it just needed a fuse and a relay!

thanks for any and all replies :)
