Engine swap advice please

Hi,

I have 3 Berlingos, but only need one. 

Now here's the issue. While all three are 2.0Hdi engines, number 1 has a slight difference. The other two have a sort of mechanical pulley and cable mechanism for the throttle mounted above the engine on the left hand side, while number 1 doesn't have this. I'm assuming number 1 may be a slightly newer model with an electronic module for the throttle.

Can anyone shed some light on this? I want to use number 1 engine in one of the other cars, but will the throttle difference cause me any major issues?

I'm a simple Land Rover guy... take engine out, put new one in... no electronics. I sense I am about to embark on a complicated journey.

Thanks in anticipation,
Marc
