ka throttle body on sr

[devonkyle77]

ok ive gota dohc ka tb going on an s14 sr, so i can keep cruise control.
one thing i have noticed, is that the sr throttle body inner diameter is much smaller. will the larger inner diameter create a problem, as i am running a very oem setup.
also the way the hoses hook up is different.
finally, the throttle position sensors are different, which i guess means i will need to be splicing wires?
can anyone shed some light on this?
it just seems the nico writeup about this was so vague, and made no mention of these things i have noticed.
