Here is a schematic which my dad & I devised over the course of two hours for
the power mirror wiring on our 1992 lesabre, as we couldn't find any
wiring info to handle this issue.
That's our/my website, and that folder will let you see & get all of the pictures & diagrams
The wiring harness for the power mirror switch was acquired through
Rock Auto, and the wire lettering scheme was embossed onto the plastic.
Here's a written breakout of the wires & their locations/purposes.
B= Common Left/Right Motion(Splits to both sides)
C= Common Up/Down Motion(Splits to both sides)
D= Left Side - Left/Right Motion
E= Left Side - Up/Down Motion
F= Right Side - Up/Down Motion
G= Right Side - Left/Right Motion
H= Positive 12V
Now Assuming that all of the power mirrors are wired & color coordinated the same, that would connect....
B -- Light Blue wire of Both Mirrors
C -- Green wire of Both Mirrors
D -- Gray wire of Drivers Side Mirror
E -- Dark Blue wire of Drivers Side Mirror
F -- Dark Blue wire of Passengers Side Mirror
G -- Gray wire of Passengers Side Mirror
In our circumstance we hooked up the power and ground inline with the
power window Power(Pink) & Ground(Black) wires which are nearby in
the door. The fuse/circuit should easily handle the minor load of
power mirrors, even if you were using the windows and mirrors at the
very same time... a rarity I do suppose.
