wiring schematic for dual radiator fans.

What width radiator you running? 22" or 26"???

I had the same problem with a 22" radiator and thought the fix was the electrics and a shroud. I could not get the 10" to mount directly to the radiator because it was not big enough. I made up the shroud and it mounted up great, but I had over heating problems with it. I could not get enough air flow thru it so make sure you have plenty of holes cut for air flow thru the shroud and fans.

Otherwise try running the Hayden clutch #2765. Its shorter than the Mopar clutch and may allow you to run your mechanical. That is what I swapped back to after the shroud deal.

If you want the wiring here is just one way to do it.. Scroll down. I do however recommend using a fan controller and relays.
