Fiesta MK6 zetec s with, it seems, focus 1.6 engine fitted, help needed please

[Mark 05 Fiesta zs]

Hello all,

Had the misses fiesta in for a PAS pump and all hell has broke loose! 

Seems the engine is not the original, been bodged in, welded up downpipe, missing various brackets, pas pump pipes have been hacked to fit, two buckled wheels, broken bumper etc etc

First up is the PAS pump but i need to know what engine is in there, what is the easiest way to confirm this? engine code? it looks as it should from the front/top but there garage was barking  on about having one belt, not two, so guess they mean the ancillary belts?!?! 

if this is a real zetec s fiesta engine, then the one fitted has the pas pump higher up and there's a hard line plumbed into the top. not like the pic at all!

Then work through the list till its done.

I've plenty of mech skills but no knowledge of these cars, so any help is appreciated!

stay safe, Mark.
