Converting from manual to electric?

[londondan86]

I tried to do this conversion, I changed the mirrors, switch and inner door looms but it still didn't work, turns out the door to body loom didn't have the wires.

But yes both sets fold forward

Is that all that's needed? What about the mirror on the passenger side, I assume there must be around 4 signal wires goin to it.
If this is the case, it shouldn't be too hard to wire in a common live feed to the switch.
