FX holden

[MY53FX]

I have an FX with a VN 3.8 and need a little help with a wire that comes from the fire wall and reaches the block my only concern is this cable is RED it doesn't go to the starter motor or alternator any help would be great thanks

What is on the other end of the cable? Does it go to a switch, guage etc?

Firstly, you don't have an FX, you have a 48-215. No such thing as an FX.

Trace the wire back and see where it goes.
