The D4BF Engine and the D4BH Engine are quite similar in most ways. The difference is the D4BH has an Electronically Controlled Throttle Valve which uses a Stepper Motor, an Accelerator Pedal with Potentiometer and an Electornic Control Unit to control the operation of this.
The D4BF Engine is an old fashioned Thorttle operated by a cable from the pedal!
I suspect t he wiring required for the D4BF won't be in the vehicle because there was in effect no need for this extra wiring!
I think your best bet would be to have the two engines sat together and see if the manifold fitments are the same and then use the block and head from the D4BF mated with the Manifolds from your existing Engine. As lone as the Manifold Fitments are the same then you should get away with it although I suspect the later engine may have had EGR or something added so may be slightly different!
You would have to stand the two engines next to each other and check the mountings for the Manifolds are the same and all of the other mounting points for everything else. If you can use your existing manifolds etc. with the new Engine then I don't see a problem.
If the Manifolds are different then you will have issues and it will become too costly and too involving in puttimg in new wiring etc.
