Hello. I purchased a Nissan Head unit online. It was scrapped from a vehicle, so I don't know exactly what vehicle it was taken from.

I want to power it on independently in my garage so I may test its functionality before trying to resell it. I tried to identify the power pins and connect them to my power supply, but it won't turn on. Can you help me?

Yep, there are four grounds and two power inputs which I have marked in the radio wiring diagrams below. Check out the images (below). Let us know if you need anything else.

Hello, thank you for your reply. There are two main connectors on the device I'm working with, one of which seems to be a standard 20 pin connector, and the other a more complex 24 pin connector.

Would power have to be supplied through both connectors? Do you know the pinout of the 24 pin connector for this particular D A 22 J unit? Thank you again.

They don't show the connector views for this just the terminal ID but it does look like both connectors must be used, can you see the ID's on the connectors?
