Key assigments with the goflight GF-T8

Hi guys can any one help me I want to assign the GF-T8 switches to my pmdg744 but I am not sure what key assigments are use. All i want to do is assign taxi,landing lights, strobes,becaon nav lights with out using the mouse. I know I can do it thru FSUIPC but I can't see where in the PMDG menu where u can change these assigments. If I use standard FS assigments then nothing works when I am usuing the PMDG 744.Cheers Craig(captainc)
