I put them in my 1996 Defender!
Hi
I mounted the front actuators horizontally onto the door strengthening rib on the outside of the winow. ie between the glass and the door skin. There is a rotating thing for the key lock and connected actuator rod to that. I tried mounting in the bottom of the door before but kept fouling the window or trim. Higher up this way for forwarding too. Wires run from a notch filed in the leading edge of trim to gap in dash trim.
I agree that wires should twist rather than flex. They will fatigue unless really special flexible cable is used. I used some plastic woven braid sheathing and filed rough edges as well. 6 months and all is well.
I do not have pictures and hate busting those clips each time i take the door trim off. I now keep spares but ...
