civic LX doesn't have ABS. only EX and SI have it .

in general you'll want to look for allot of breake lines (little pipes) that are going in the same place and different from the master cylinder (the thing with the break fluid resevoir on top of it in the front of the driver)

as far as I know, hondas/acuras have the ABS modulator on the passager side in the engine compartiment.
