c1 and c2 represent sensors that when active create ground (relay pin 85)?
does relay 3 have battery hot at pin 30?? in bigkat's graphic. does the high speed and low speed work together or is one off when the other is on? |

Yes, c1 & c2 are grounds which when are controlled (in my case) by the ECU. They provide the ground at their respective relays. #30 pin on #3 relay is getting it's "hot" from fan #2. The fans run together at hi or low speed. Or, they are off. They do not run independent of one another.

I went ahead and totally rewired my dual electric fan setup using three relays and BigKat's diagram.
The only thing left to do is purchase a thermo switch to screw into my rod simpson radiator where their is an extra port that is capped at the top of the radiator. I brought the plug with me to my FLAPS and they couldn't figure out which one (application) that would screw in...GEEZ! I thought that would be the easy part. Any ideas how to source a 200 degree sensor that is the right size for my radiator? Attached image(s)
