In the bottom of my inner primary I noticed a sensor, it looks like a temperature sensor, but no one I talk to has ever seen this before. Is there any one here who can tell me what this is and if needed, and also how to order a new one since 1 of the wires was broken. The bike is a 1999 Ultraglide, EFI FLHTCU-I 88 cu in tc. And sorry for my poor gramma, english is not my 1st language. BR Jon Vikan Hole where the sensor is located Sensor in primary cover Sensor

Not stock. One of the previous owners installed it.
Concur, if it was me I would just put a plug in there, making sure it was sealed up good and call it a day. Don't really need to know the temp of the primary fluid.
