i have been using the dc controller for three years now on different vehicles. it will start the fans at about 10% and slowly work its way up. when the a/c comes on they go to 50% but it is not instant. the current draw hardly ever spikes at all. i also got the voltage sensing light so i can tell how much they are on. also i put in a a/c condensor sensor from madenterprise.com. when i start cruising it will cut the signal from the a/c. so when i am going down the road the fans never come on.

I never got around to it but once thought about trying the relay in the Painless kit.
Part# 30106
Fan Relay w/thermostat - Gen III
Designed specifically for all GM Gen III engines as inexpensive protection for your electric fan. Provides constant voltage, protects from voltage and amperage spikes and keeps fan from back feeding through the system. The kit comes complete with GM Gen III thermostat, 30 AMP relay, 30 AMP circuit protector and all mounting hardware.
Weatherproof Gen III Kit Available part # 30127

I can put another relay in to change the a/c signal from a + to a - but I'm not sure if I want to use 5 relays to get the job done.
When the AC turns on it has a 12V correct, but when it is off does it go to ground?
From what I read it should trigger from a 12V or Ground or a change from 12V->Ground or Ground -<12V
