Starting the engine - wiring

So, for the first time for 5/6 years the engine has not been turned over. Its been kept under a tarp, outside.

To the cutoff valve on the right. It then connects to the coil on the positive side (left terminal). Also, not seen it a wire running from the positive side of the battery.

The wire on the right side of the coil runs to the condenser.

Below is the oil pressure switch.

I've just connected the interior light to it. One end connects to the battery, the other, the switch.
