Identifying power connectors on a USB Charging PCB

[akshay_b]

Hello all!

This is Akshay and I'm seeking a little help from you electronics expert! I have purchased a 45W USB C charging + data module for my car to replace the older 20W USB C module. The PCB has two connectors, 1 for data and the other for power. While the data connector fits perfectly, the power socket has some swapped connections that are not working with the old connectors. The LEDs on the new PCB work, but data+power delivery is not working when connected to a phone.

Can you please take a look at the PCB and identify the order of these connectors on the new PCB? I know this is a wild request but I'm a total newbie in electronics and I don't have any tools to test it out.

Thanks a ton in advance!

On the old one +ve seems to be pin 1, and ground pin 2 - on the new one +ve seems to be pin 1, and ground pin 4. If you look the ground connections are clearly visible.

Thank you, Nigel Goodwin! Is it possible to tell the connections of pins 2 and 3 on the new one?

Presumably they are the data connections?, but I've no idea which ones they are.
