Exterior
Side-view Mirror Wiring Diagram
I first give all the wire color codes on the "car side" of the connectors and then the "mirror side". Keep in mind that this is for my '90 928S4.
"ASCII graphics" stuff below will only look correct if you use a monospaced font.
Right Car Side (passenger side in U.S.):
6-pin connector (drawn from wire insertion side):
/-1--2--3--4--5--6-\
| O O O O O O |
+------------------+
1: white/gray [adjustment motor 2]
2: blue/red (bridged to pin 4) [adjustment motor 2]
3: black/blue [adjustment motor 1]
4: blue/red (bridged to pin 2) [adjustment motor 1]
5: gray/green [heating element]
6: brown [heating element]
4-pin connector (drawn from wire insertion side):
/-4--3--2--1-\
| O O O O |
+------------+
1: gray/yellow [motor 2 position potentiometer]
2: green/brown [potentiometer common end A]
3: brown/yellow [potentiometer common end B]
4: yellow/green [motor 1 position potentiometer]
Left Car Side (driver side in U.S.):
6-pin connector (drawn from wire insertion side):
/-1--2--3--4--5--6-\
| O O O O O O |
+------------------+
1: white/brown [adjustment motor 2]
2: blue/black (bridged to pin 4) [adjustment motor 2]
3: black/red [adjustment motor 1]
4: blue/black (bridged to pin 2) [adjustment motor 1]
5: gray/green [heating element]
6: brown [heating element]
4-pin connector (drawn from wire insertion side):
/-4--3--2--1-\
| O O O O |
+------------+
1: gray [motor 2 position potentiometer]
2: green [potentiometer common end A]
3: blue/brown [potentiometer common end B]
4: yellow [motor 1 position potentiometer]
2-pin connector for temperature sensor
(terminals are visibly numbered, I think)
1: brown/green [temperature sensor]
2: blue/green [temperature sensor]
Mirror Side (for both Left and Right Mirrors)
6-pin connector (drawn from wire insertion side):
/-6--5--4--3--2--1-\
| O O O O O O |
+------------------+
1: white
2: blue
3: black
4: red
5: brown
6: brown
4-pin connector (drawn from wire insertion side):
/-1--2--3--4-\
| O O O O |
+------------+
1: gray
2: green
3: brown (original flag mirror) ..or.. pink (aero/GTS mirror)
4: yellow
If you want to look at the electrical diagrams in the shop manuals, here are
the relevant places to look (again, this is for the '90 model year):
- For mirror motors and potentiometers, i.e., for
everything related to the 4 and 6 pin connectors:
"928 S Model 90 Sheet 7"
"(M537, M538 Seat and Mirror Memory",
all the stuff inside the rectangle
with upper left corner at A-52
and lower right corner through D-58
- For outside temperature sensor, i.e., for
the two pin connector:
"928 S Model 90 Sheet 4"
"Instrument Cluster and Senders"
D-21 and D-22
