I have some PC's that have a touch screen mouse. These PC's are in a manufacturing environemnt and do not have keyboards installed. Does anyone know how to create a jumper that I can make and install on system to make it think a keyboard is installed?

It's not that simple.

The BIOS actually queries the keyboard controller to verify that the keyboard is both present and functional.

The easiest way to "simulate" a keyboard is to cannibalize an old keyboard.
Remove the controller board and cable.
Mount the controller in a small "project" box and connect the cable to the PC.
The BIOS will think that a keyboard is connected. Users will not have a keyboard in their way.

If what you're trying to do is simply keep the computer from coming up with a "No keyboard present" error, also check the BIOS settings - I've seen several computers that have a "Keyboard Present" setting so you can turn off this check when it boots up...

Following on from the last answer, in BIOS there can be a setting HALT ON ERRORS select NONE or not keyboard or similar wording.
