Most fans are more then 30 amps. The best way to run that fan is with a relay also when using a relay you will not have to worry about burning that switch up.
also you can run this off your cars relays, use a switch SPST works great, ground one lug to ground the other to run through firewall to your fuse box and FAN relay's lug 80 usually... basically you are just grounding the ground lug in the relay and bypassing any sensors that activate it by grounding the ground lug.. many cars have 2-3 relays, 1 relay to run the cooling fan for both AC and temp, then you have your hi lo speed relays ac/temp combo, you could tap those relays as well, this works well if all your relays and wiring are all functioning but you don't like when the computer tells the fan to go on, and most cars that's late in hot hot 115 degree weather... this style here does work well (perhaps a relays isn't a bad idea) if you just cannot figure out why your fan will not kick on for either the AC or temperature, like when it gets hot it wont kick on and cool it down, or it doesn't automatically go on when you turn on AC like it's supposed to.. in this case its usually relays or fuses, or bad fan but sometimes the ECU does fubar and that's a hassle for sure, so are bad melted plugs and or fuse blocks... or you just don't have the time to fix.. try jumping the relay, you can jump the relay right at the block on the ground lug that works too.. but then it s always on as its not switched, but for emergency what not gotta go try that.. some fans kick on when the temp sensor is unplugged good way to troubleshoot see if fan does work..
Right on! Yeah, it already getting hot here in Georgia. This really takes all the guesswork out of wondering if your fan is running or not. Much appreciated Brother! Peace
Well, I'm here for the same reason. Same toggle too. lol.. Idk how yours has turned out since but,, I'd wrap that entire switch with black elect tape. I only used one toggle, and it gets hot in between me cycling it. I turned it by accident, and it touched metal and wow the fun began. And I had it wrapped I thought well, just not that much.. I know now though. Just done this again this morning. Cheap fix. Still only one switch. My fuse wouldn't transfer enough power, so it's just, fan / bat / switch. Like just one of yours looks there. They loosens sometimes by themselves, so it's always good ideal to safety wrap them well. Dig this.. I done it because my fans stopped coming on. I have a Chrysler T&C. My right slide door ripped my wires in half to control the door. When that happened, check eng's on.. Brakes on, obs on, and air check on tires on... lol... so I thought fans were the same.. Shorted on me too... But after wiring this bad boy up the 2nd time. They know are on with key on. Makes no sense. ahhaha hope you enjoyed that. Later.
I have 3 wires on my fan a small skinny black one I'm guessing is the accessory, then 2 others that are negative and psot8ve. Where does that accessory connect dawg?
Where do i conect the postive cable and the negative cable and accessory bro cus im not comprehending this at all. U said basically hook up the 12volt cord to the accessory???? Aint that the positive
Another way is to run the radio accessory wire etc ( Activates when you turn key) ..to the factory relay thats under the hood ...there is 2 relays, primary and secondary. You have to tap into 1 wire for each relay that goes from PCM ( there is only 2 wires that go to PCM to Relays 1 each ) to the relays it uses very little power to activate the relay so it can send the main power 40 amps to the fans! By doing this Your fans will turn off and on with the ignition key ! And by pass The PCM to Relay Control and it will not have conflict either! If you want a switch but do not want to turn the switch off and back on every time you use the car..do the same thing I described But add a switch before it goes to the relay. So from Radio Power wire or alternative (Ignition Activated Power) To switch then to the tapped Wire that goes from PCM to Primary Fan Relay and Secondary fan relay.. Remember that its the skinny wires under the relay not the big one thats the 40 amps leave those alone! Doing this ,If you have the switches off ,the car fans will work normally and when you want to activate the fans. Hit the switch and it will by pass the pcm and will not have conflict. When you turn off the car with the switch still on it will turn off because its getting power from the radio power wire wich is ignition switch controlled. When you turn the car on when the switched already on remember that the radio will not turn on until 3 seconds after you hit the ignition switch thats good because if its cold outside you dont want to crank the engine and turn fans on at the same time and stress the battery because of the cold weather. This is for 94 95 96 impala/Caprice should work for other similar year gm vehicles and some what same idea for other brands! If you already have to much electronics on the radio accessory wire ..You can also put a relay going to the radio power accessory wire ! th-cam.com/video/86_ocEp6mHI/w-d-xo.html
i am trying to wire my fuel pump to a switch on 69 mustang, so i have black and red wire coming out of the fuel pump, i know the red will go into the Accessories prong on the switch, should i put the black coming out of the fuel pump to the frame or wire that up-to the switch as well ? or do i need to run a ground from the battery to the switch it self ? please help
SharkNT Gonzalez cool deal I’m going to be doing a update video on this showing how to use the fans and how to hook them up to a relay thanks for watching
@@TheLsSwapGuru can I get a link to that video. I just bought a 1995 z28 camaro with a 5.3l ls swapped into it and can get the relay hookup to turn on the fans when I hook up the relays with the wires on the stub that powers it. The only problem is they stay constantly on when plugged in and I have to unplug the relays to turn off the fans. How do I make it so they only turn on when I turn the key on
all the add-ons on my project car:hood extractors fans,fog lights and extra high beams are hooked to a secondary 12V battery with switches on the dash.
Is there any way to wire this so you can manually control the 2 speeds on a fan? I currently have mine hooked up directly to the battery where it goes battery - 30A fuse - 35A switch - fan but would love to be able to switch between low and high speeds on the fan since the high speed is a bit too loud and isn't necessarily needed at all times.
Wormanatti idk brutha are u using a 35 amp switch? and don't use a fuse use a relay boss...I apologized for the late response was at a church event really late
No sweat I do the fellowship thing too. Im up now so I can make it on time. Going to crack at it again. I just realize it was a 20 amp toggle. Going to swap it now for 30+. Start from scratch. The fan motor has two wires blue, black. Maybe the blue is the power or receiving power also so that maybe blowing fuse I'm thinking. I have a red wire to acc. black to body ground & darker red to positive terminal. The blue is tied to the harness relay from which the fan originally comes from but that's why I'm going to switch. Baby been inconsistent. I brought new harness, temp switch, new relays. Forum says the pcm is likely the problem not trying to change that one.
Wormanatti make sure your using 10 have wire to fam... blue goes to the signal terminal and the power from the acc gotta to the power side of the switch u have Instagram? I can dm u how I did it on the wagon
I have to remember my instagram password. Let me ask you does this sound right. Positive terminal to power on switch. Load to black wire on fan. Ground to body of car. Blue wire of fan goes where?
+kevin cortez this set up is very easy no relay on this one it's a 3 wire hook up ground power and signal autzone sales them for 5.29 a switch it's 35amps
You dont have to but you can sold the car and its still working switch nevwr burnt out but adding a fuse would be better to prevent that from happening...this was just sonething quick I did to get my car running you can also add a relay to the fans
My jeep still over heats and I've replaced the thermostat and temp sensor. So do you know if I'd lose power and not get everything out of my fan if I ran fan to ground, ground to switch? Sorry I'm naive when it comes to electronics.
Joseph Freeman no worries its just a 3 wire hook up ground ignition and signal wire if you car keeps getting hot check the basic first...make sure you have enough coolant make sure your system is bleed properly and make sure the radiator cap has 15-18 pressure...if that dosent work just hook your fan wires up to a if ignition key hot our have this switch installed as a override
He didn't and he has a lot of voltage. Drop running all that heavy gauge wire front to back and heat is another issue as well the fans won't live as long as they should and I didn't see any fuse on it either it's a recipe for disaster
I bought a new fan and harness and tried to splice(?) The 3 wires from the harness close to the power supply were the the 3 fan wires are but it's not working somebody help
Try hooking the fan up to the batter to make sure it works 3 wires 1 to the pos battery one to the negative and the other is fan signal if it dosent come on its a bad fan if it do cut on lmk so i can further help you out thanks for watching
@@TheLsSwapGuru I was trying to connect it to the fuse for the radio in power supply fuse box I bought the fuse adapter for it,.if I should use the relay I will.
Said it plenty of way if you want swit hes this is the quickest way THE RIGHT WAY would be to hook it to a relay to the pcm/ecm or relay to a thermo switch
A bro that's nice I been wanting to install a second fan to my impala because I see that when you do burnouts and donuts when its hot outside my temp will go up to the halfway mark never really liked that only because it's to close for me and don't want to blow a head gasket and also I been wanting to install and second fan on my Tahoe too because that thing is set to run halfway from the factory and it gos over if I sit to long or if I'm towing something but my question is can you hook up the power wire to the cigarette outlet so you won't accidentally leave it on and kill your battery?
can I do this on a 01 crown Vic, I can't even drive my car because it over heats the fan won't work I got one from the junkyard and had to rig it but my wires get hot quick

Richard Bradley flex-a-lite makes a manual fan specific switch that can handle their fans.
He said it was a 35 A switch - but the wires, joints etc - make sure wiring is large enough. Relay is good too for this.
So a 25 amp will it hold
@@maryjanemoore-lx1lg no. 30 or more and you're safe.
Make sure your switch can handle it.
Make sure your writing is at very least 16 gauge.

Why do you need ground on your switch and not connect it on the car body instead?

Did you buy another pigtail for your setup or did you cut all the electric setup and went manual.
DatBoy Slick yep cut it and ran it manual this was just a quick fix but I switched it to a relay shortly after
all the add-ons on my project car:hood extractors fans,fog lights and extra high beams are hooked to a secondary 12V battery with switches on the dash.
joe coquerre sounds dope
how did you hookup secondary battery like to see video on it thanks
thanks I been trying it all day so I don't need a inline fuse or nuthn?
nice fookin car, clutch too
Why didn't u use a relay switch.
doesn't it kill your battery? (parasitic draw)
No. The hot is going straight to the switch leg, when it's off, theres no way for it to draw unless it can return thru ground.
Is there any way to wire this so you can manually control the 2 speeds on a fan? I currently have mine hooked up directly to the battery where it goes battery - 30A fuse - 35A switch - fan but would love to be able to switch between low and high speeds on the fan since the high speed is a bit too loud and isn't necessarily needed at all times.
I'm curious as well. I'm planning on doing this with my heater. Did you find anything out?
What gauge wire bro
What Guage wire?
Did you already get rid of your original floor shifter handle ?
Where the wire u hook to the battery
Good look video really helped
Can you do this to a dual fan radiator?
Sure can
You get voltage drop and heat because the switch is too far from the battery.
This is why relays are useful.
