Today I was only able to work a short period. I bought some 63/37 solder at Radio Shack and soldered the 5 wires from the MAC-8 Trim Servo to the shielded cable that will carry it to the instrument panel. I covered each joint with shrink tube, and although you can't see it, there's another larger shrink tube to the right that I will pull back and shrink (with heat gun) after the servo is installed and the grounding wire is properly attached.
