When I plug in the cable into the DLC and move the plug slightly on the HD15 port on the HP tuners box ever so slightly, some of the gauges on my cluster move the far left and some lights pop up. Appears to be a ground issue or power issue on one or more of the connection points on the HD15 plug that is on the HP tuners box itself. Is it common that these are wearing out after being so old? I've already verified continuity of all 4 wires leading to the data link connector port both which is ground for pins 4 and 5, ACY fuse for pin 16, and Pin 58 on blue PCM for pin 2. All fuses and relays are good. Battery power is full. Voltage at the DLC is 12.4v
Wiring diagrams I used for my car to verify no issues with the wiring:

Note in this video here that when you move the HD15 connector, the gas gauge drops and power is lost to the HP tuners box. It obviously won't be recognized by the software when that happens. If I hold the connector real still and plug it in, I get connection. Not ideal for logging and a risk of bricking when flashing. What specific HD15 type connector do I need so that I can repair this? Anyone know the specific part number? Anything else I need to be aware of in this unit that could be causing the issue? Don't want to upgrade, I just want to repair this one.
