Fan Wiring For Dual Fans-Two Or Three Relays?
How many relays did everyone use on their dual fan set-up? F-Body computer. Is there a link for this? Thanks
I used one 40 amp relay for each fan with 10 g wiring to the battery and fans. I also used electric grease on each contact point to reduce heat from arcing.
RUN WAT U BRUNG!!!!
Run three, here's the wiring diagram.
1991 Silverado-L33 5.3L, 212/218 .557 .562 115+4, ASP under drive pulley,180* thermostat, 90mm truck intake w/ LS3 throttle body. Shoenfeld conversion headers and duel Flowmaster exhaust. Performabuilt LVL 1 transmission and 23-2500 stall converter.
Nice, easy to read, diagram. Thanks. But why run three relays...versus two?
Also, who sells good quality pigtail harnesses, for Bosch relays? thanx
It uses 3 to tie both together and control both fans speed, 2 would only run 1 fan at high speed only, and the other at low speed only. This way shows that when the low speed fan is engaged, it turns on the other one also and vice versa. Please correct me if Im wrong.
RUN WAT U BRUNG!!!!
I have ls1 fans... I have 2 relays, but 1 switch, both come on full blast when I flip switch (which realistically is only when I'm sitting in traffic or have AC on)
On buddy's truck, 1 is always on, he has a switch for the 2nd.
blown transmissions are about as useful as 97% of the guys on this forum
