you would have to by pass the fan switch possibly wire directly to motor i would try hooking all this up in the engine compartment temporarily to see if it will work

1st locate the ceramic speed control switch 2nd run your test leads from there to where your going to mount the switch leave the ceramic speed controller in the air box just determine your hot lead and negative lead,hookem into riorand the try it give a test make sure it doesn't get to hot if not then mount this switch where you want it on the dash or make a separate panel to go under the dash with easy access for the driver.

Change the frequencies on each fan's receiver and then set them in the remote to match. These are the little leavers/dip sticks inside. Make sure you turn the power OFF first! We just installed 4, all on different frequencies!

Have a large gauge wire running directly from the battery or alternator to one of the large posts on the relay. Connect the other large post to the radiator fan. Then, run a small gauge wire from your fuse block (usually on a circuit that turns off/on with the ignition switch) to one of the small posts on the relay. Then hook the other small post to ground.

This is a GM based switch, it comes with the connecter to wire into your existing wiring, you will have to splice it in. Not a plug and play but easy to install with supplied wiring diagram.

You need a separate switch. Fan has a small junction box with knockouts for wiring connection.

Passanger side under the glove box. Remove the cover, remove the round fan, top right side. You will have to splice the wires into the old plug.

I installed a three-way switch so the exhaust fan was separate. I imagine there are other ways to do it.

pull out the blank switch and if there is 8 wires on the plug it will work if its less then youll have to add 2 wires check out the tundra forums they have pics and instructions

This is how I use it, but you'll need 14/3 wire from the switch to the fan to do this. (Usually black + red "hot", white neutral , and bare copper ground). Most switches are only wired with 14/2 wire which only has one hot (no red)

David, i am sure you could wire on in before the fan switch. You must be aware, this fan motor runs at a high velocity and is quite noisy. But we love it because we used to have a mold problem in the bath it is installed in, and after installing it-no more mold!

Sorry but beyond my skill set. I had a fan and simply wired this one where the old one had been. Wish I could help.

For me there was one already installed to control a fan. The existing one went bad and locked into full power so I replaced it. There was three wires from my fireplace. One is power that is looped with a thermostat and the other is a neutral. Should be simple swap out, resolder the wires and it's ready to go.

This is not a DYI for the timid. This part is an OEM replacement. It will work. If you can read the wiring diagrams on your furnace, you should be able to set the dip switches using the instruction manual in the box. If you dont know how...STOP AND CALL A PROFESSIONAL. Also, if you burned up your board, replace your capacitor. Cheap swap for a common cause of board failure.

look at your old remote. there should be a distinct number combination on a "dial". simply put that same number combination on your new remote to be able to control your fan. no electrician needed.

This unit will work but will take some wire configuration. To accomplish this task, you must have some knowledge background in automotive electrical. If not, my suggestion is to take it to a Pro Shop better safe then sorry of losing your vehicle by electrical fire.

Just connect a wire from the positive side of the fan motor to one lead of your indicator light. Connect the second lead from the light to ground. I used a red LED lamp purchased from Radio Shack and mounted it to the fan's On/Off switch plate. Remember to connect the wire to the fan motor itself, not to the positive side of the thermostatic switch. Connecting to the thermo-switch will only tell you there is power in the circuit, not whether or not the fan itself is running. I think I used 18 or 20-gauge wire for my installation as the LED draws very little current. Good luck and Merry Christmas.
