If you are talking about PWM cables there is a Chief Delphi thread about this topic that offers good advice.
We’ve found that zip tieing them tightly close to the connection helps hold them in. It’s harder to pull out all of them than just one.
Zip tie them in a few places, zip tie them around the microcontroller if you have to.
what we did, although it makes the connection between pwm and pwm extension semi-permanent, we took a ziptie, slid it through two of the three pwm wires, then made it go around the connection, and slid it two of the three pwm extension’s wires, then ziptied it closed
hopefully i can get a picture up after our team returns from the Peachtree Regional
