Funny, I just finished doing this a few minutes ago. The temp sensor is located at the back of the front cylinder behind the horn. It looks kind of like a spark plug with an oval plastic end. You will need a 3/4" deepwell socket to remove it. I am sure there is a special sensor tool Harley sells to remove it, but I modified a 3/4" spark plug socket with a 7/8" hex on top by cutting 1/4" off the top and bottom with a cutting wheel for clearance between the cylinders. You remove the horn, pull back the rubber cover, lift the clip that snaps the wire in place, pull out the wire, slip the socket over the tool and use a 7/8" wrench (or a ratchet) to break the sensor loose, remove the tools and spin out the sensor out by hand. Reverse the procedure to install the new one. Be careful not to crossthread the sensor as it has fine brass threads. This is an easy job.

On a 1999 Harley Heritage Classic, the speedometer sensor is located on the transmission. Specifically, it is mounted on the left side of the transmission housing, where it detects the rotation of the speedometer drive gear. This sensor sends signals to the speedometer to display the motorcycle's speed accurately. If you're having issues with the speedometer, checking this sensor and its connections is a good starting point.
If you don't have a speedo cable on your front wheel, you have a speedo sensor. I believe that change was made in 2000.

The crank sensor on a Harley-Davidson motorcycle monitors the position and speed of the crankshaft. It provides critical data to the engine control module (ECM), allowing for precise timing of fuel injection and ignition. This ensures optimal engine performance, efficiency, and smooth operation. If the crank sensor fails, it can lead to performance issues or prevent the engine from starting.

If a running Harley gets laid on a side, either while moving or stopped/idling, the tip sensor kills the engine. the ignition switch must be cycled off then back on to start.
tell me how to replace my engine temp sensor
none on engine, pull temp sensor in oil pan
replace the bad sensor and it will turn off.
You need a engine scanner and hook it up and it will tell you what sensor is bad.
