s14 and s15 will work to turn your car yes, and bolt on yes, but not not really work.
There are 2 reasons
#1 the horn wont work, b/c on s12 and s13 they have a ring that the horn slides on with a recieving brass piece to make the conection, the s14 and s15 like all modern cars have a spool of wires that feed through and electrical connection along with the cruise function/air bag.
#2 the turn signal turn off wont work, so if you put on your blinker then turn the signal will stay on b.c. the s14/15 are again differnt and use 2 small bumps on the column.
So now u know!
I have a jdm splash hub for my s14
