I have been looking at this post for some time...And am adding a few things for my setup....Since I live in TX and sometimes stuck in traffic for a long tim I am adding a 2nd relay a temp sensor for fan 2 and LED's that i am going to have in my dash for verifying fan 1 and fan 2 running.
First fan will run constantly
2nd fan will kick on when temp reaches(???) (not sure what to set this too any suggestions)
I will attach a wiring diagram.
Build parts list
2 Taurus Fans
2 12v 30/40a relays
2 lights and screw in holders Light one to show fan 1 is working light 2 to show when 2nd fan engages
1 temp switch adjustable surface mount (mounting it to the center of the radiator should work but will be testing the temp ranges of the radiator..Any Suggestions)
