II rolled my 2000 disco 2 and now I'm transferring all parts into a new shell of an 03 disco 2. Ive run into a problem, this part is different and so is coinciding plug




Honestly I don't know what this is or what it does..

This is its plug



This is the plug and piece that was on my working 2000 car






What I would like to know is if there's a way to wire the old plug on or something? My engine is not secondary air
