We report measurements of the high-field (H{le}30 T) magnetoresistance R(H,T) of pure and doped YbInCu{sub 4}. A hysteretic transition is observed which we take to be the field-induced variant of the first-order valence transition observed at 42 K in YbInCu{sub 4} for H=0 T. Applied pressure suppresses the valence transition to lower temperature. By properly scaling the (H{sub v},T{sub v}) data extracted from the resistance measurements, we can collapse all of the pressure-dependent data, as well as that from doped variants of YbInCu{sub 4} at ambient pressure, onto a universal H-T phase diagram. This suggests that a single energy scale is associated with the valence transition. {copyright} {ital 1997} {ital The American Physical Society}
