Hotpoint Oven Timer Replacement

Has anyone successfully installed a WB19X1006 timer? I put one in a Hotpoint RJ745G*T7. It doesn’t work. The instructions are confusing, at best. There is no sign of life from the timer (clock does’nt light). The bake/broil all works fine (as they did when I started this whole mess). In my old timer, WB19X5269, there were 4 Red Wires in corner, 1 Orange next, 4 Whites and the fourth corner blank. Anybody got a clue what goes where? Anybody got a schematic of the timer? Help!
