Am doing a JX to AAZ upgrade and I have read here about an aux water pump that exists on the JX. Now for some reason I can't seem to locate it on the JX.
So two questions. Did all JX lumps have them or only some? And secondly, the same goes for the AAZ...can't seem to see one on there either.
A pic of one would be great or if someone could point me toward a link so I know what the heck I should be looking for.

Much appreciated.
