With the above steps complete, our main power and ground wire is connected to the circuit breaker. We will cut the wire to length and add a Deutch connector once the fan is mounted in the car and the proper length to the power lead that we made is set.
Here we can see the ¼” gap to the shroud from the delrin spacer which serves to further insulate the electronics from heat.
Since the circuit breaker is mounted fairly low in the engine bay, to quickly see if it has been tripped, we painted the reset lever bright pink.
We cut the three wires from the fan to the factory plug and crimped and soldered wires to each end, which will power the fan through our new wiring and use the existing plug as triggers for our new relays.
After being crimped and soldered, we again used adhesive-lined shrink wrap to seal the connection and to prevent it from being stressed.

Radiator fan wiring upgrade they auxiliary relays what wires output to the fan either number or color it’s not clear thank you for your help
Have a customer with a 96 wanting to do this upgrade to his cooling system, any idea where the cooling fan may be available?
That’s weird. I’ve always been taught to crimp ring terminals on the cut side, so it forms a B-type crimp that secures the wire. Well, whatever works!
good evening i have a 1999 viper GTS and i just got the radietor from you do u by any chance sale the hole kit for the fan to make it work better please let me know so i can buy ti thanks
need to but a water pump for 1997 dodge viper. please call me 505-316-0182
surffun1915@aol.com i did evething u did but when it hit 190 the fan starts 5 min later the 60 amp trips fan goes out car will get hot i had to wait to cool to re-set the 60 amp ignition protector
What temp does the fan kick on? Did you change the low or high speed fan temp threshold by flashing your ECU? If you’re tripping the 60A circuit breaker, then you need to troubleshoot and find what is causing the excessive amp draw.
Is the Bosch relay with the 332 209 151 number the same relay? Stats look similar to the one you have installed
Those appear to be 30A relays vs the 50A relay that I used. I would recommend using the part number for the 50A relay.
can u send me more detail about the wires evething look nice but i can not see every cable where they go to make shure i conected right i need the order or a better pictures can u send me a diagram i got all the parts thanks
