Hi, I believed the first one is the oil level sensor, you can confirm this by disconnecting this socket and try turning ON your ignition if your oil indicator in the gauge will not lit. The other one is the brake fluid level sensor, disconnecting this will lit your indicator at the gauge permanently.

1st - Oil pressure sending unit. - If the oil pressure is too low, will cause the oil light to come on in the cluster.

2nd - Should be the a/c clutch wiring. Engages the a/c compressor.

3rd - Brake fluid light. If the level is low will put on the ebrake/brake fluid level low light. (shares one light) If its on and the ebrake is not engaged, then check the fluid.
