help small 12v circuit relay etc

[tim20vt 0]

if any one can help heres what i need to do.

 

i have a 12v live for 10 mins on ignition off.

it runs my pump and fan for 10 mins. this is fine.

 

 

what i need to do is run my pump on ignition on but not my fan.

at the mo if the pump runs so does the fan.

 

i also need the 12v feed to not get power from the 12v ignition off 10 mins when the ignition is off.

if you get me?

 

so in simple terms it shud be pump and rad on for 10 mins on ignition off using existing wire.

and just pump constantly on on 12v igniton on.
