Installation of 968 Mirrors On a 1986 944 Turbo

Daniel Popovich

Time:

2-3 hours

Tab:

$200-$865

Talent:

****

Tools:

Metric hex key set, soldering iron, solder, wire cutters

Applicable Models:

Porsche 944 (1983-89)
Porsche 944 S2 (1989-91)
Porsche 944 Turbo (1986-89)
Porsche 944S (1987-88)

Parts Required:

968 mirrors (used or new), Radio Shack male and female 6-pin connector kit (2)

Performance Gain:

More stylish mirrors (depending upon your preference) on your 944

Complementary Modification:

Install the 968 exterior door handles to match

The installation of 968 mirrors onto 944 doors is really quite simple.

The first step is to find a set of mirrors.

Second remove the old mirrors. If you rotate the flag style mirrors about the pivoting base you will find a single bolt. Remove this with the proper hex wrench

Mirror removed from door. I chose to cut the original connectors off both the car door and the new mirrors and install new connectors. (you may be able to find the original connectors and just re-wire one side)

I purchased this simple 6 pin connector from radio shack, you will need a male and female connector for each side of the car. The pin extractor pictured on the right is a necessity if you are prone to not getting things right the first time and having to move wires around to different holes in the connector. The instructions on using these connectors are printed on the box.

Each wire should be soldered into place to ensure a good connection. I recommend completing all the wiring ahead of time so if there's any doubt about which wire goes where you can plug them in and make sure it's doing what it's supposed to.

If for some reason you would like to remove the glass (perhaps to get better acquainted with the wiring of your motor)

Note- the small bulb sticking out the bottom of the mirror in between the two arrows was some sort of light, I am not sure what it is used for, I suspect it is to tell the driver that the heated mirrors are on? This has two purple wires leading to it which I chose not to connect.

you will need to unlock the mirror face by inserting a flat head screwdriver into the bottom of the mirror through the hole in the rubber (flag style) or the metal case in the 968 mirror (right arrow). There you will see teeth of the plastic locking system (left arrow) if you rotate this fixture it will release the glass face and you will be able to pry it off with little difficulty.

The two wires connected to the glass are for your heated mirrors. The other four consist of two wires each, for the up and down motion of the mirror and the side to side motion.

The wiring was as follows for my car (1986 944 Turbo)

944 Door 968 Mirror

White ------------------------------ White

Black |-- 'White/Brown ------------------------------ Blue

Ground--| Brown/Black ------------------------------ Red

| -- 'Black ------------------------------ Black

When removing the old connectors note the wiring, the ground is used twice in two different sockets, there is a small 2 inch black wire running off the ground into another socket so both side/side and up/down motion can share the same ground.

The two other wires are for the heated mirrors and were all brown on both ends on my car.

If for some reason your wiring is different you can easily determine which wire from the door controls what by using an ohm meter. Switch the ignition on to the accessories switch and apply power in one direction using the selector that you would normally adjust the mirror with. You will find voltage running through the two wires corresponding to the direction you chose. The polarity is reversed to make the glass move in the opposite direction.

With both ends wired correctly you need to just plug the connectors together and reattach



The finished product looks great!

BrechtV Comments: Does the mirror defrosting still works after connecting to a type1 with above diagram with relay?

  Followup from the Pelican Staff: If you wire the mirror heaters in to work, then they will. You will have to install the relay, switch, etc. - Nick at Pelican Parts  
TROYLAIR Comments: YOU GUYS ARE GREAT FOR TAKING THE TIME TO SHOW US THESE STEPS. IT MAKES THE JOB SO MUCH EASIER NOT TO FEEL SO ALONE IN TRYING TO ACCOMPLISH THESE TASKS.

carsontc Comments: couple of corrections in the comments below, and here I'm adding how to wire 968 mirrors into an 944 early.

------------------------------

To get your 968 mirrors working on a 944 early or 924 for that matter, you just need to add an SPDT 12v relay inside each door total 2 relays to the existing wiring.

Steps 1 & 2 Connect:
Door’s BROWN chassis ground to one side of the coil…each door.
Door's WHITE +12v when left/right motion selected to the other side of the coil...each door.


Driver’s Door

Step 3 Connect:
Driver Door's BLUE wire to Mirror’s BLACK & to Mirror’s BLUE connect ALL 3 together

Step 4 Connect:
Driver Door's BLACK wire to SPDT relay term. 30 the center/common relay contact

Step 5 Connect:
Driver Mirror’s RED to SPDT relay term. 87a the normally CLOSED relay contact which will control up/down motion

Step 6 Connect:
Driver Mirror’s WHITE to SPDT relay term. 87 the normally OPEN relay contact which will control left/right motion


Passenger’s Door…slightly different wiring then the driver’s door

Step 7 Connect:
Passenger Door's BLACK wire to Mirror’s BLACK & to Mirror’s BLUE connect ALL 3 together

Step 8 Connect:
Passenger Door's BLUE wire to SPDT relay term. 30 the center/common relay contact

Step 9 Connect:
Passenger Mirror’s RED to SPDT relay term. 87a the normally CLOSED relay contact which will control up/down motion

Step 10 Connect:
Passenger Mirror’s WHITE to SPDT relay term. 87 the normally OPEN relay contact which will control left/right motion

DONE !

carsontc Comments: jd...he means the door wire harness’ Black is a jumper/strap to door wire harness’ White/Brown. So the 968 mirror's Black wire AND 968 mirror's Blue wire can BOTH connect to the harness White/Brown or to the harness Black as they are electrically the same no matter what the polarity is depending on switch position.

The word ‘Ground’ can be confusing as it could either be Ground or +12 volts depending on the joystick switch position…so ignore the word ‘Ground’ where he indicated it.

From the schematic it looks like:

The White and Blue wires go to the motor that controls left/right motion.

The Red and Black mirror wires go to the motor that controls up/down motion.

The switches positions determine whether +12volts; or ground; or nothing, goes to each of the wires.

Door Harness------968 Mirror
White ------------ White
Black or White/Brown ---- Blue
Black or White/Brown ---- Black
Black/Brown --------- Red

jd Comments: Thouhg I appreciate the time you spent explaining this process, your wiring diagram does not make sense?
I have an 86' as well and I could not make sense of your connection chart?
White --------------- White....got it
Black |- White/Brown --------------- Blue.?
Ground-| Brown/Black --------------- Red..?
| - Black --------------- Black...?
You could really simplify this by charting which 968 wires go to which 944 wires. Only step one makes sense.
