'98 Grand Cherokee 4.0 w/182k

Well my ABS light has been coming on periodically for the last month, so I dropped it off for diagnostics & the stealership tells me its the 'ABS pump & control assembly.' I only went here for diagnostics & plan to have the work done elsewher. Carpartswholes.com has an 'ABS valve block & pump motor' for $477.12, but I'm not sure if this is the same as the ABS pump & module assembly.

Any ideas insight is appreciated.
