These are the correct colors. Pink is hot and is fused. Dark Blue (DBL) for oil pressure goes thru a firewall connector to the sender. The brown for gen goes thru a different firewall connector to the voltage reg "L". They are completely different in operation and are not connected in any way except hot and ground. Concentrate on the oil first, it is the simplest. It will be grounded to the motor to light the light when low press (start up) then open the ground to open the circuit and light will go out. It is sometimes referred to as a switch because it is a normally close pressure switch (sender). So if you have hot to the socket when not running (and pressure has gone down) and switch on, and the bulb is good and you have grounded the wire that you took off the switch/sender terminal and the bulb lights but does not go out after pressure builds, then the sender is bad....or the connection AT the sender is bad/loose/corroded/dirty. Figure that out first.
