Is there a way to fit the cruis control to the s50b30 engine?

I have all the harness and the control units on my car, from my ex M50 2.5,
but I don't know what I will have to change, to make it work, since the unit on the throttle body is, of course, gone :)

I saw some pictures with M3's and to acceleration cables on the same bracket, but I guess that it takes more than that to make it work again.

Anyone with experience with this, I was enjoying my cruise control back in the days :evil2

Thanks
