Juno-106 3-prong grounded IEC connector wiring

Working on my Juno-106 and lost the 2 prong power cord so I figured I update it to the 3 prong IEC socket. However I can’t find a good reliable wiring diagram. I’m assuming the left connector is the white wire and the right connector is the black? The center needs to be a green ground like the red lines in picture ? Any advice?

Add tags before posting: brand + model + (optional) fault
e.g., korg, models-korg-m1, no-power
If your model isn’t listed: use models–tbd (e.g., models-korg-tbd) and post the exact model in the pinned “Request a new model tag” thread. We’ll add it and retag.

• Model & revision/OS:
• Symptoms (what changed, when):
• Tests already done (voltages, parts replaced):
• Photos / audio clips:

To be honest: If you have to ask this question, then you should not touch that - not to think that you would change that.

These two two-pole cables are available on eBay. Buy one and don’t put your life or the lives of others at risk.

Best to use a multimeter and check continuity from the mains plug pins to the connector.
