Again I’m not very well versed in hardware at this level. So I’m not sure if this was mentioned in messages and I just inadvertently left it out because I’m an idiot.PCI-e x4 requires 4 pairs of data lines for both directions plus a pair for the clock at minimum. So that is at least 18 wires.
All of the power ones can be derived elsewhere, the detection, SM and JTAG pins I am unsure of.

How big would these types of wires be? Like would the be similar in circumference if a Xbox 360 mod chip wire? 18 wires is… a lot.
