just finished my sr20det swap and auto to 5 speed swap, and now the horn doesn't want to work? what could have happened? it worked before the swap! i checked fuses, they are all good....

Who needs a horn?

Check to see if the wires running to the horn are getting power.

how much do i have to take off to check that?

Ground the lead in the column, also check for power at the horn relay in the fusebox.
More than likely you just unplugged it by accident. Usually a FMIC install requires moving them, people rarely remember to plug them back up or even reinstall them.
