Installing A S4 Engine In A 1990??

Can I use a S4 Engine in a 1990 if I use the S4 ECU and wiring harness? Will the oil lines, cruise control, etc., match up?

Doesn't Anyone Have ...

... an opinion?

Ixhave a S4 that I am taking out of my wrecked base model and I would like to put in a 1990 that needs an engine rebuild. Any comments would be appreciated.

it would be easier just to use the S4 block and bolt all the S5 parts on to it.
