The clip for my head temp sensor is missing and it keeps vibrating off causing the engine to shut down. is there any place to get replacement clips/connector assemblies?

 

ebay... junk yard... Nissan... Checker... AutoZone.... Napa.... shall I continue?

or you could just use a bit of imagination, to make something to keep it on... like wrap it w/ a garbage bag tie... or just go to the junk yard & cut one off that's in good shape.

 

NAPA carries the OEM style plugs, but they are expensive. I got all of mine from the A/C Delco Driver... They have accesories like mad on those big battery trucks you see driving around. If you see one parked at a shop... go hit up the driver. They sell 'em for about 25% of what NAPA want's for them.

hey where is the heat temp sensor and when it vibrates off does it not even turn over

 

The head temp sensor is on the head where it meets the block just below and in front of the closest spark plug to the firewall. If it's disconnected your car won't run. There is also a "coolant temp sensor" up top by the Thermostat housing... are you sure that isn't the one coming loose?. If it's disconnected, your gauge won't work.
