Brake switch Parts replacement?
I replaced my brake switch on 2008 f450 with Delco part
from rock auto, they look the same but only thing I can see
different is the last letter in part number. What is difference
in the part numbers ending in AA and AB?
If it works you don't need to worry.
Exactly, especially since you have an older model. Many times part numbers change or are superseded by new part numbers for the same part. Hope that helps! Jim
