current requirements

We need way more information.  Way more.

This is a constant to momentary setup.   If you have a signal wire that goes positive for a while and you only want that wire to control a relay briefly, this is what you want. 

Constant to Momentary Output ( link)

The capacitor allows the coil of the relay to be energized until the capacitor stores a charge, thus de-energizing the coil. The resistor bleeds off the charge of the capacitor when positive voltage is removed from the other side of the coil. You can increase the output time by simply changing the value of the capacitor. This one will give you about a 1/2 second output.

The following diagram will take a short pulse and make it longer. 

Pulsed to Steady Output ( link)

If you have cornering lights and want them to come on only when your turn signal is on and you do not have a steady output, use the following for each side. This will give you a steady output while the turn signal is on. Increasing the size of the capacitor will give you a longer output if needed.

That depends on the resistance of the coil.   But I can not see a 4 meg resistor allowing enough current to even think about triggering any relay, regardless how small it is.

Sorry I completely overlooked that the first time you asked it, Oh wait a minute
