GM connect and cruise ls3 wiring harness cooling fan relay issues

[Hdduramaxman]

I just bought this 68 camaro as a already finished ls powered protouring car......After taking delivery there has been some issues with the car and its not really a surprise to me that in this day 60k doesn't get you far when it comes to buying a protouring muscle car. My biggest issue thus far has been the cooling fan relay in the GM fuse box. The way the previous owner has it set up is that both fans on the Ron Davis radiator go from two wire to one wire before being connected to the large blue wire exiting the fuse box. Im wondering if the two fans are to much for the output of the blue wire and if I should add the the spal cooling fan relays normally sold with my radiator. Let me know what you guys think.

Thanks

I would go with the Entropy two speed controller or the DCC pwm controller. Both would be quieter and use less current most of the time.

Gmpp dual fan key and also pick up the AC bump kit.

Made for our setup and very very easy to do. Gmpp controller, ls3 l, dual spal fans and works like oem
