I am installing several sensors onto my engine (EGT, CHT, Fuel Pressure, Oil pressure and temperature, Manifold pressure, etc.)

 

The CHT sensors came with a ring terminal that had a nut bonded to it.  It was actually easy to crimp a ring terminal onto the other wire and screw the two together.  The EGT sensor had regular ring terminals but provided screws, nuts and lock washers.  All the other sensors have bear wires.    

 

As all of these sensors are in areas with high vibration (either directly on the engine, or on the fire wall) I was considering either using the above method of screwing the rings together, butt splicing, or AMP Mate and Locks.    Screwing the rings together or using Mate and Locks would be easier, but I think the butt splice would provide a reliable connection.  

 

Is there another method that would provide both maintainability and reliable connections in high vibration areas?

   Consider knife splices under heat-shrink.
