Extract from my website regarding fitting a BL Mini Wiper motor to a Ford
Escort based loom:

Wipers

Assuming you are using a BL wiper motor, you have the problem that the wire
colours are different to those on the Escort.
The Escort has five wires to the wiper motor, in two groups - two power
wires (green and red, from the column stalk) which have a grey plug, and
three other wires via a black plastic connector to a headlamp-type plug on
the wiper body (these are the motor earth and the park wires).
The BL motor also has five wires doing the same jobs, going to a 5-way multi
connector with 4.8mm female spade terminals which plugs into the wiper unit.
You should cut off this connector with as much wire to spare as possible
when you get your motor from the scrapyard. You can remove the wires from it
by poking a small pointed object into the business side of each terminal -
there is a small cut-out - and bending the non-return lug flat. This allows
you to use new terminals. Or, you can leave the wires in place and make
soldered connections to the Escort wires.
The big question is, which Escort wire to which BL wire? OK - BL black is
the motor earth, which goes to Escort brown / white. Escort green is low
speed, and goes to BL red/green. Escort red is high speed, going to BL
blue/green. Escort black/violet is the park power supply and goes to BL
green. Escort black/brown is the park earth and goes to BL brown/green.
If your Escort has a wiper delay (marked on the column stalk, plus you have
a large red relay like a flasher relay) then this will work fine with the BL
motor. Its wiring isn't detailed in the Haynes manuals, so I can't help if
you don't have one but want to add one.

Cheers

The wire colours you mention are those in the wiring loom itself.  From
what I remember, if you look at the wiper motor, the wire colours from
the inside of the motor to the attached plug/socket are different, and
may well be as the poster said.  If I had a spare wiper motor I would
check, but I don't have a spare one. (And there's not much of them
visible either between the plastic body of the socket and the insides of
the motor).
