Location of fuse for ODB constant power?????

[George M]

I am installing some AMP-Research powerstep running boards. They will not deploy when the door is opened. In going through trouble shooting with them they believe that I need to check the fuse that powers the odb.
I cannot find where that fuse is.
Can anyone help identify that particular fuse?

Thanks
George M
