Replacement PSE - Reprogram or not?

2003 S430 - I have confirmed that the pump motor has gone out, and I'm getting ready to replace the unit this weekend. When I replace it, will I have to have it reprogrammed? If so, If I keep the old electronics and just replace the pump, will that keep me from having it reprogrammed?

Thanks in advance.

When I replaced the PSE in my 2005 S55, it was plug and play; no programming needed.
Cheers,
Jeff
