Time relay for pump and fan.

So this looks fairly straight forward…

My AC & Recirc buttons will be redundant now I’ve removed the AC from the car. So I was going to use one for the spare fan and one for the pump. Different buttons, different relays (same though) so I can press both after I finish with the car or press just the fan if sat in traffic. I also plan to secure both relays under the dash as its sat all over the desk next to me. Any suggestions?
