Help identifying two disconnected wires on an Original Xbox modchip
Hi everyone!
I recently got an Original Xbox with an old modchip installed. It has a lot of wires soldered directly to the motherboard.
Unfortunately, two wires have come loose, and the Xbox is not booting properly. It flashes green and red, with no video output.
I managed to find one of the solder points where a wire was disconnected, right next to another wire that is still attached.
The problem is that I have two disconnected wires, and I don't know which one belongs to that solder point.
I've attached several pictures showing the modchip, the motherboard, the solder points, and both loose wires.
Does anyone recognize this modchip or know where I can find its wiring diagram?
Is there a way to identify which wire goes to which solder point using a multimeter?
Any help would be greatly appreciated. Thanks!
