The speed sensor in the trakhamr self-install kit seems to be one of the most difficult things to get aligned and working.
The sensor is located on the passenger side
There is a nylon boot around the sensor and is siliconed to hold it in place. I used channel locks to twist and break the silicon grip and pull the nylon boot out. This side with the arrow pointing at it should face the yellow tone ring, from the point of the sensor, is towards the inside / differential. I didn't get a pic of it, but looking into the hole where the sensor was, you'll see the yellow tone ring.
The below picture shows the side that should be pointing at the wheel side, away from the tone ring and differential.
Loosen the sensor in the nylon plug so you can move it around. Push in the plug. Then slide in the sensor til it hits the axle spindle. Then pull it out juuuuuuust a hair. That should do it. Don’t worry about silicone until you try it. It should fit pretty tight as is.
Let me know if there are any questions.
