Ok so im currently doing a 1.9 swap and i have a question about the one fitting on the back of the engine. I ended up swapping the t3 turbo and manifold to the 1.9 and this fitting is different.
Sorry for the sh!tty celly pics and the noob questions.

Is there anything i can do to make the fitting off the 1.6 engine work? or can i use a rubber hose?
Also, There was something attached to the small stock turbo that i have no idea what it is...

Once again sorry for being a noob. Do i use it with my t3? or take it off.
And there are wiring connections at the other end for it.

Alright sorry for all the bad pics... Hopefully this makes a little sense, im also swapping the complete mk3 harness with the motor aswell as the dash.
The car



Thanks again! I just wanna finish this swap.
