Altima Fan Setup

[undesiredshoe]

I have some altima fans that im going to put on soon and i was reading up on ways on how to wire it up. Theres the manual switch method, the "On when ignition ON" method, and the thermo switch method. I like the thermoswitch method the most, so i was wondering if i could do something like this...



Its kinda messy but ill explain it

Since each fan has 2 speeds, i want to wire both fans to come on at low speed and both to come on at high speed. The low speed would be connected using a relay. The relay switch would start at the ACC and through the relay, then through a thermoswitch. Then the 12V would come from the battery and split into two wires to power both fans on low speed.

The high speed circuit would come from the AC Fan Plug. The positive wire would split into two wires and connect to the other positive on the fan and be grounded.

If this would work, then the low speed would come on at 180* and stop at 170* via the thermoswitch and just incase the low speed isnt enough, the high speed would come on at around 200* via the ecu's AC control thing and hopefully stop at around 180* for the low speed to take over again.

Sorry if this is really basic stuff but i just want to get your guys opinions
