Hello. I recently purchased an rx7 FC (87 NA) from Oklahoma and have been trying to get it to start today... I was removing the spark plugs and noticed this unconnected wire just dangling... looking through the manual I couldn't find anything about it... thoughts? For what it's worth the engine tries to crank but hasn't started yet... (squirted some AT fluid in the top spark holes, gonna do bottom tomorrow when I have sun)
Thanks

The small blue one looks like the temp gauge sender.



The white one looks like the oil level sensor. Should attach to the sensor in the oil pan in front of the motor mount.

The white 1/4" male spade connector looks like condenser (i.e., capacitor) connector. The condenser is bolted to front of clutch slave cylinder on bell housing. Note that replacement condensers are no longer available from Mazda. The round barrel connector looks like connector to 5th gear / reverse switch. This switch has 4 wires with 2 being barrel connectors for this backup light portion of switch. Maybe the other wire broke off at the harness?
