I need a simple step by step on how to wire the cooling fans to a switch. Although my fans work fine on thier own, Summer is comming and i'd like to have that extra piece of mind. Any help would be appreciated.


Its a 305 tpi a4 with dual fans bone stock if it helps

Run a wire from the control side of the fan relay ( the dk grn / wht wire , bottom RH corner in diagram ) to ground through a switch
If you want both fans to work off the switch , then wire the control side of both relays together

Not for your year but you get the idea

Maybe a dumb question but, the fan relays, where in the engine bay are they? Im pretty sure i know one is on the firewall on the driver side by the brake booster... Is the other one there too or somewhere else?

There is a button at the top of the page

Your link didn't work but I'm familiar enough with the search function. Found what I needed. Thank you for all your help my friend.

I traced the wire that comes off of the temp sensor for the fan then I spliced on a wire to that ran it to the firewall to a switch and ran that switch to ground. Grounding that wire will energize the relays and presto fans on command
