Hello John,
I adapted a mk1 Ford Ka unit to do the job – I suspect it’s almost identical to other Fords. The wiring is 2 core to each motor, and the polarity is changed by the switch for either up or down motion.
I’m pretty sure it’s not possible (or certainly very difficult ) to just change the motor unit because the lift wire is coiled within a geared housing attached to the motor – If you are brave enough to dismantle an existing unit from your car it may answer whether a motor swap is possible. I changed to electric because my manual winders had the ‘bend the track’ modification, which is ultimately doomed for failure because the lift wire cuts into the track – If the tracks on your car are modified in this way (bent 90 degrees) that could explain the slow movement. If it is helpful, the
conversion covering the parts needed and how to make the changes without bending the track was in issue 176 (March 2021) of Complete Kit Car magazine

Subject: [Quantum Owners] Electric Windows
I have recently been doing quite a bit of rewiring on my saloon (factory built). I noticed the wiring cable for electric windows (looks original) is 4 core (Red white black brown) going from cabin into door cavity but at each end of this cable 2 pairs are joined so effectively 2 core cable connecting motor to centre console switch. Wondering why 4 core cable was used in build? - possible wiring of extra door switch? . The wire gauge looks same on 4 core and switch connection cables so extra load capacity seems unlikely. Currently the switches are wired directly (no relays). New switches and relay operation are going to be fitted.
John,
I hope this is the image you remember on the club website.

I can confirm that MK1 KA window regulators can be used. I wrote an article, published on Quantum Mechanics Issue 95 (Autumn 2018) explaining how I fitted them in a 2+2. Later I Andy Heaton and I fitted some to his saloon. The link Steve provided shows how to shorten the runner. The other issue is the KA regulator cables are shorter than the Mk3 Fiesta 3 door units so the motor mounting holes need to be relocated.
