Converting an E-33 to operate from overhead wire

[Denverrails]

I have 2 E-33s and have added DCC to both. The instructions state that the pantographs are not wired for operation. How can the pantographs be wired to pick up current from the overhead wire for the motor? I have converted other locomotives to run from the overhead by connecting the "Red" right rail pickup wire to to the pantograph. How can this be done with these models? Is there spot on the circuit board where a wire from the pantograph can be connected? Has anyone on the List done this?

Thanks!!

Is there a wiring diagram for the HO E-33 model?
