Ditto, the wire in mine is also scavenged cat3, or cat 5. it depends on when in the run I made it. I ran out of spare cat3 and had to dive into the cat 5.
Mad editor!!
Also, from the 1668PDF in re: probe wire length
Quote:
For remote-sensor distances longer than 8in, or in particularly
noisy environments, a twisted pair is recommended.
Its practical length is 6ft to 12ft (typ) before noise
becomes a problem, as tested in a noisy electronics laboratory.
For longer distances, the best solution is a
shielded twisted pair like that used for audio microphones.
For example, Belden #8451 works well for distances
up to 100ft in a noisy environment. Connect the
twisted pair to DXP_ and DXN_ and the shield to GND,
and leave the shield’s remote end unterminated.

Given, cat 5 doesn't have shielding. for a true testing environment one might want to use the suggested belden cable.
And my design doesn't have the EMI stuff, naughty me. TBH, I didn't know at the time how the hell to make EagleCAD do a ground poor
