What sensors are these? They are the Ones with the sit connectors

 

idk what a sit connector is but i from looking at the picture, it looks like the orange one is an injector and idk what the purple one is. your fuel temp is on the far left of the secondary fuel rail fyi and its green.

if you can take a better picture, you can get better help.

 

brown=secondary injector
purple=primary injector

what about these

 

 

Those are located on the air control valve, which works with the airpump for emissions purposes.

 

Ok thank you.
