The use of 4 core cable may well be for redundancy but my guess is as
you say they just used what they had ;-) - that fits with a lot of the
other additional wiring where it appears they only ever had 2 wire
colors in stock.
All 4 cores seem to have god continuity so at least I don't have to
replace that as it looks like a pig to do.
Not sure if my window switches are Ford - they look like the generic
rectangular electric window 5 pin switch with spade terminals - maybe
they have already been replaced once.
I have not measured the load motors draw but my early version copy of
build manual show 30A fuse on supply so relays seem a better way than
direct - as you say need 2 per side
Looking at regulators I can now see mine have the 90 degree bend at
bottom (what a bodge solution that was LOL) so most likely a failure
waiting to happen if not already in progress!
I recall seeing a drawing detailing window mods (I think you were the
authorJim) but cannot find it now.
@Martin
The KA mk1 units look like the best option to me - easily and cheaply
available and newer. The cable sections are shorter than the the
Fiesta MK3 so the motor mount position would have to move but that is
easy enough. Same motor reverse polarity operation via switch (or
relay in my case).
With regard motor change I think it should be possible (but probably
not cost effective) - the motor just drives a worm gear but that of
course needs to be same on both units. I have taken regulators apart
before to replace cables - most of them just wind the cables around a
grooved nylon drum. I think in theory you could shorten the cable
instead of fitting spacer on sleeve (need to solder on new nipple in
correct place).
I have now confirmed that I have the 90 degree bend units so these
definitely need to be replaced.

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

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.
Window movement is really slow. I don't think this is due to dirty
glass friction etc. so maybe motors are tired. The current setup
is using Bosch motors which I guess is probably Ford Fiesta Mk3
original type (see pic). If the mechanical side of regulator/cable
is ok I was wondering if just motor can be replaced on these? (a
lot of Bosch units look very similar although slightly different
part numbers)
If I replace complete regulator with motor which donors have
owners found best or easiest to fit? I think originally modded
Fiesta MK3 units were fitted but others have mentioned MK4 MK5?
can be adapted as can Ford KA units.
John
