does anyone out there know a way to manual wire into the fans to have control over them with a switch inside the car, i know slp makes one but im doing a lot of driving this weekend and cant get slp by then, thanks

 

I tried using a switch to pull down the relay like the computer does but it kept registering on the computer as a fault. I took another relay and wired it parallel with the existing fan relay and use that to turn on the fan. Since it is beyond what the computer can sense-no fault code. You are going to have to have a wiring diagram to know what color wire to attach to.
