What do these things do?

[grizz]

On the MX5 loom, just found these two items.

Anyone know what these two items actually do?

Wired into the loom on the drivers side.



And no, they are not labelled.

Thank you.

They're the fuel tank and carbon cannister solenoids.
Your new fuel tank doesn't have the necessary plumbing for them.

They're connected because I don't know if the ECU notices if they're not there, and so we don't keep looking at random unused electrical connectors. They are removed from the bulky components they are associated with.

Thanks Nick.
