The 1 wire coolant temp sending unit connector under the dizzy on my crx was hanging on by 1 wire and came off. Where can I get another connector? Can I find a new one somewhere or do I just have to get a used one? Can I use one of those bullet connectors on it?

 

You can use any connector you want. OEM ones are cheap though. Junkyards have plenty of them for free most of the time.

 

You can use a regular bullet connector on the one wire sending unit connector, it works fine.

If you're ever looking for new oem style connectors for other sensors, and you don't want used ones that you have to solder, Chasebays sells individual connectors with new pins and weather seals.
