Hi,

First post on this forum, so forgive if i'm not familiar with some of the do's and dont's.

I have a Thunderbolt 2 to VGA connector which I wanted to convert to USB type C. I've very crassly sliced the connector open without thinking, which has led me to discover that both these structures are very different.

As you can see, the Thunderbolt 2 has 3 small cables and 3 cables consisting of 2 wires each. The USB C only has 4 connectors (it's a dumbed down version, normally it has more), 2 for power and 2 for data, based on the USB 1, 2 and 3 protocol.

I've watched this video, but can't seem to find and equivalent for thunderbolt 2 -> usb C.

Anyone has any idea?

Kind regards

I would like to solder the USB C adapter to the original cable so that i'm able to connect my VGA screen to my PC. I already cut off the original thunderbolt 2 connection.

The other side of the cable has a female VGA connection.

BUt yeah basically this is what i'm trying to do, without having to buy an extra cable and having 2 adapters connected to each other. Just directly solder the wires to a USB C breakout board.
Your end goal is to make a cable that is USB-C male to VGA female by using a cable that was Thunderbolt-2 male to VGA female. Like this. Right?

Here is some starting information, the pinouts of the two ends.

Can't seem to open the first link in Belgium..
Thanks for those 2 pin readouts! Looks like I got myself into some deeper shit than I was expecting. I'm only seeing 9 cables on my cable, and the pin readouts reach 15 and 20 points. Maybe because of multiple grounds...
Will try and educate myself.
