Thank u! I spent so much time researching the fans and so much time trying every wiring combo that I could dream up. Now that I've I've setup a 4.9, 5.0 and the 5.8, I'm thoroughly convinced that this is the right way to go. Next on the list is the Fiance 's 4.8 Silverado and my son's Sierra 5.3. I have the Bully Dog brand new in the box for the Sierra and can't wait to see how much we get between the e fans and the Bully Dog. My ex step son just paid me to do the fans on his '65 mustang. That one was fun since there was only room for one fan. Had to grab a Toyota two speed fan to work with the aftermarket ac they installed. Another happy customer. Wish they were all done with the motor out of the car like the '65 was.
Not trying to brag, just enjoy sharing what I've learned doing this mod. I have some other experience with a certain air filter setup........nevermind. I don't want to cause the elders to lose any sleep arguing about that subject. Lol

I'm waiting on a trip to Alexandria in the next couple of weeks. Lol
The hardest part is removing the stock fan clutch. It took an air chisel to remove mine. PIA!
As far as failed controllers go, I have a double relay setup on mine. Failsafe. If the controller goes out, main power in to either of the relays can bypass the controller. If either fan goes out, seizes, the relay for that fan can be unplugged. I've seen numerous threads about the high dollar controllers failing. I've had my $18 advanced auto parts controller in place for well over a year with the only issue being a wet relay from power washing the motor get stuck in the on mode. Unplugged the relay and replaced with the relay I keep in my glove box and was back to normal. The only downfall to the relay sticking on was a cold radiator. The extra time spent wiring a relay for each fan prevents a load on the controller. The controller is only a trigger for each fan relay. No load on the controller, IMO, greatly reduces stress on the controller and extends it's life. If a load related failure occurs it should come to the two relays that I have installed and negate controller replacement. Overkill? Maybe. Reliability? Absolutely! Failsafe? Absolutely!
Edit...here's my wiring diagram. I've since cleaned it up. This was just my initial setup. I've added a cover to the circuit and wire loomed all of the wiring. Much better protection now and cleaner nest of wires. It looks much more complicated than it really is. Nothing to it if you take your time and test how each of your fans work.
