I've had this old rfguys cable for years and it never would connect to any of my P7100/P5100 or 700P/Pi radios, that I had tried using it on at the time. The number on the cable indicates that it's compatible with the LPE/P7100/700P/Pi radios however, the pin arrangement isn't quite the same as the OEM L3HARRIS programming cable. Could this by any chance have been an attempt at modifying into a keyloader cable, even though it doesn't seem to connect in that regard either?
