Todd --
Now all you need is the SPAL PWM fan controller.... it kicks on fan #1 at half speed -- and ramps up the speed as temps climb - then when #1 is full and temps keep going - Fan #2 comes on full blast... Hook your A/C trinary into it and it waits until head pressure is reached and kicks BOTH fans on full - and continues to run them for 30 seconds AFTER you kill the A/C to cools things down...
I just bought another one off AMAZON for $124
With this controller you only need ONE fan relay - for fan #2
Small package easilly hidden and all weatherpack connectors...
