Description:
This procedure will walk you through the simple steps for replacing 
the Outside Air Temp. (OAT) Sensor in your mirror. Your mirror 
may be slightly different from the ones in the pictures, but the steps 
will be the same.
Mirror styles this procedure applies to are:
West Coast and Moto Mirror or Road Scan
Tools/parts needed: 3/16 drill bit
Electric/cordless drill
Pliers
Rivet gun (needs to fit 1/8 rivet shank)
Parts Kit SK-1525
Step 1:
Disconnect all power to the mirror.
Step 2:
Remove the mirror from the mounting brackets as you would 
normally do.
Step 3:
Place the mirror on a table where there will be ample room 
to work. If needed remove mirror and harness from truck. 
NEVER try performing this procedure on a platform or 
Ladder.
Step 4:
West Coast Mirror
Remove 1 screw from the top, and one screw from 
the bottom. The side brackets will come off and the 
mirror parts can be disassembled.

Bottom View of Mirror
Moto Mirror or Road Scan
Drill (3/16 drill bit) off the heads of all the rivets 
along the bottom perimeter of the mirror holding the 
bottom plate on. This will allow the bottom plate 
with the OAT sensor to be removed. You may have 
to take a punch and gently push the rivet bodies 
inside the mirror so the plate will come loose. 
Remember to remove all the rivets from inside the 
mirror.
Step 5:
Unhook the OAT Sensor from the wire harness.

Step 6:
Drill out the 2 rivets holding the OAT Sensor to the plate.

Moto Mirror or Road Scan
Step 7:
Put replacement sensor into position and use replacement 
rivet supplied to reinstall sensor.

Step 8:
Reconnect sensor to harness.
Step 9:
Reassemble mirror using the rivets supplied, or on the West 
Coast reinstall the screws until tight.
Step 10:
Reinstall mirror on truck.
Step 11:
Reconnect power to mirror.
Note:
In the parts service kit there will be different length rivets. 
You may not need them all. One kit was created to service many 
different mirrors.
The 2 longer rivets are for the Sensor. The short ones are for
the perimeter of the bottom plate.
