Retro-fitting parts

[AlexNR]

Hi all

Just wondering if anyone has retro-fitted parts to their connect.

More specifically I have manual windows and mirros and would prefer to upgrade to electrics.
The cables that connect the manual mirrors seem to be stretched and not very responsive to inputs, and the window winder handles are on their last legs so either way I need to spend money.

One curiosity is whether the wiring exists to do this and the wiring looms are standard.

Anyone with any information, I would be grateful for advice.

TIA

EDIT:

Oh balls, just realised i posted in wrong section ... apologies ..
I can't delete so hoping admin will move to correct section.

I've also just found out I can't remove the driver's door lock as none of the keys fit the lock.
I can get into the passenger and rear door, but driver's lock appears to be a different key.

Any advice welcome
