Shop 968 TRANS SPEEDO DRIVE
968 Speedometer Drive KitRemove the 6 bolts attaching the drive axle to the transmission on the left side. Remove the original dust boot support strips (some have two, some have three) that the bolts passed through. Replace those strips with our 968 two piece cogged drive wheel. Re-install and re-torque the 6 bolts.
You will be required to manufacture a bracket to hold the speed sensor to the transmission as this is not supplied by us at this time.
In this picture, you see a bracket attached to a lug on the transmission. There is a hole on the other end of the bracket that the sensor passes through. The sensor has two jam nuts allowing you to set the gap or distance between the sensor tip and the wheel. Set it to .8mm or approximately .030".
The speed sensor has a round tip in the center about 1/8" in diameter. Position that with your bracket so that is aiming at the outer 1/8" on the cogged drive wheel.
Wiring instructions for Speedo kit:
Cut the original 3 pin connector off that used to clip on to your old transmission's speed sensor. Attach round terminal connectors to the blue/red wire and to brown wire. Connect these to the two terminals on the sensor. It does not matter which terminal the brown and blue/red wires are connected to as the sensor will produce a signal in either orientation.
You should cut and tape the remaining green/white wire as it is a 12V source for the old sensor and we don't want it touching anything.
