I forgot to clarify on the video that the gauge of wire used is determined by the amps of the accessory. Items using 10 - 15amps can use 18 - 16 gauge; 20amps use no less than 14 gauge

Hi so i will only have one fuse right as i will have one wire comin from the battary to the off switch an then one wire which is connected from my led an lights passing trough a fuse then connected to the on switch an the ground wire from the devices i can connect to my car battarys ground right please let me know also what amp do i need for the fuse what fuse can take the lights i have do u know

Good video, btw i wanna get opinion from you, im planning to set up 1 switch for 2 pairs DRL (front & rear). Power source from ACC fuse box to fuse to Switch, wiring from Switch to DRL1, use SnapLock to split wire for DRL2, then use SnapLock again for pair connection for both DRL. 1. Do we still need that fuse before Switch if the power source were already from ACC fuse box? 2. Is the power supply sufficient? 3. My RockerToggleSwitch listed as 12V 35A, is there any problem using a 35A switch for low power LED DRL(i believe its below 2A?) or do we need to find low amp Switch? Thanks much!

I would be using a relay in that circuit. Rad fans are drawing quite big amps and things are gonna get warm using your method.

[@TooBlessedToStress88]

Agreed. Relay plus 12ga wires would be my recommendation

[@JamesRazorbacks]

Yes at least use 10-12 gauge wire I used that thin wire and my switch got way to hot and started smoking

[@orlandovega6986]

Proper way is using Relays.

[@joeradler]

Thanks for this tip to add a relay and use 12g wire as my switch DID get hot using this method and 16g wire (only the load wire side got hot, though the accessory out wire stayed perfectly cool). I now understand the too-small wire problem but can someone explain (1) the overheating load wire while out wire remained cool and (2) what a relay will do to solve this problem?

[@petittrainguernsey3297]

@@joeradler Relay acts as a switch, keeping the circuit the fan is on separate. Don’t forget to add a fuse on the positive side. Wire getting hot because it’s taking the whole load for the fan and switch. Fans draw large amps so it’ll get warm if not thick enough. Putting a relay in keeps the circuitry for the accessory compact and isolated.

@@PhillipsVision alright, you mean 12v switch. But I can't use 6A toggle switch with a 10A fuse. Current more than 6A will blow my switch before fuse could do anything. Isn't it ?

[@PhillipsVision]

If it’s wired directly to the battery without a toggle switch, it will constantly be getting power. You need to run it through an in-line fuse (and possibly a relay switch) BEFORE it hits the toggle switch. You need to be able to cut off the power when not in use.

[@PhillipsVision]

Black gets grounded on the chassis. You can attach to the negative (black) terminal on the battery but chassis is better. The red is your 12v power which supplies power to the accessories, running through a fuse prior to the accessories

[@cbonesteaksauce3833]

Can a switch like this work with current in reverse? I.e. could you connect a solar trickle charger to the switch then to the battery? If so, should I wire the switch with power in (solar panel) on the “off” side?

[@PhillipsVision]

Just to clarify...you would have the trickle charger normally charging and the switch would cut off the connection? This is a momentary switch so the activation, or deactivation, would only take place as long as the switch is held down. If you want it to be able to switch on/off you’ll need a 12v toggle switch.

[@cbonesteaksauce3833]

@@PhillipsVision hey! Correct. When the car is off, the trickle charger would send it’s current through the turned on switch to the battery. When the car is turned on, the switch will be off (to prevent power from the battery going to the panel). You’re right, I’d use a toggle switch, not a momentary switch.

@@cbonesteaksauce3833 that should work

[@chaomain]

Does it matter which side of the toggle switch you connect to the battery and the device?

[@PhillipsVision]

It shouldn’t if you have just a simple 2 pin switch. When the switch is “Off” the circuit is open, when it is “On” the circuit is closed. All the switch is doing is opening and closing the 12volts to the accessory.

I’m sorry I’m lost I have a factory stereo and it’s connected to my amp but my amp stays on even when I turn the car off where can I add the toggle switch and where do I get the power to do that

[@PhillipsVision]

Did you connect the amp to a constant 12v source? If you run it the through a source that is only activated through the ignition, it will only get power when the ignition switch is activated. You could also add an in-line toggle switch that will only send 12volts when the switch in “on”. Find the dedicated 12v line going to the amp and cut it. Add the toggle there, but make sure to add an in-line fuse prior to the voltage reaching the amp. This will protect the amp in the event of a power surge. The layout should be...12v source, in-line fuse, in-line toggle switch and finally the amp. Make sure you ground the amp on the chassis. Do not connect to an existing device’s ground.

[@flynfury8363]

I think this will work for an exhaust cutout but my only concern is with an on off switch. Either on or off, one of those ways wouldn’t the power always be trying to close or open the device. In this case I don’t want to always have power going to the valve that closes or opens. Wouldn’t that burn up the motor? If so, how would I fix this problem?

[@PhillipsVision]

fly n fury use a momentary switch, not a toggle. The power will be disengaged unless the button/switch is pressed. When the button/switch is let go, the power will be cut off again.

[@flynfury8363]

Phillips Vision perfect. I knew there was an easy way. Thanks for the quick reply.

[@flynfury8363]

Phillips Vision I’ll try to keep this simple as I didn’t think about this earlier but I can’t hold the button in while I’m driving for a period of time. If holding the button in is open on the valve as soon as I let go of the button the valve would shut again or stay in that position? I need the valve to stay in that position and then on my next press of the button close the valve. How do I do that?

[@PhillipsVision]

fly n fury then just use a toggle switch “on / off”

[@flynfury8363]

Phillips Vision I thought a toggle switch would always be supplying power. I need the valve to open and stop trying to keep it open. Same thing for close. I don’t want to burn up the motor if it’s always trying to make the valve move in one direction or the other. I hope that makes sense.

Yes the fuse will help, but most overheating issues are due to wrong wire gauge. The higher the gauge, the thinner which will melt. I recommend no higher than 14gauge to be safe. Ultimately you want to know you amps of the device; that will determine the proper gauge needed.

Stay True011 it does but I normally just run an in-line fuse before the switch with the correct amps, this way it will protect my switch should anything happen.

how do i find which wires are my fan wires under the dash.when i turn off my mini van the fans dont turn off so i ben unplugging them every time.shop says 200 hundred dollars

[@PhillipsVision]

If you’ve been unplugging them, then just connect to those wires and run new lines from them to the dash

[@chaosblackstar]

@@PhillipsVision ok so i have duel fans do they both run all the time or do i need 2 switches

[@PhillipsVision]

@@chaosblackstar you can choose. I have both fans connected to one switch

[@chaosblackstar]

@@PhillipsVision ok thanks phillip

[@LTSRIDE24]

I'm totally confused... Why would they put a GROUND connection on the switch if it's not suggested to use it?

[@slurpeeslurpee69]

Umm so I’m doing a 4 switch thing to power light bars. Do I just do this 4 times?

[@PhillipsVision]

So you’re power (4) separate light bars? Do you want the ability to control them individually?

[@slurpeeslurpee69]

@@PhillipsVision Yeah that’s kind of what I am aiming for.

[@PhillipsVision]

@@slurpeeslurpee69 then you will need to connect a switch to each light, using the method in the video

Use relays or you risk setting fire to your car.

i basically didnt do the fuse before i watched this video now my car wires started smoking makes sence lucky cars ok it was for my halo rings so i basically put the wire from the halo ring one to postive an one to negative on the battary an then have another wire from the postive wires going to the switch will two wires going to the switch but add a fuse like u showed right

[@PhillipsVision]

Vlogstar Parm if they’re smoking you may also have too thin of a gauge of wire. Depending on the amps you’re drawing will determine the gauge you need.

@@PhillipsVisionright got it a little im using speaker cable but this i the lights i have i have 12v halo rings a 30cm knight rider led 12v light an 4 led strips lights which i basically connected all together which were all on to one swith if i had fuse this time is it good to add the fuse next to my battary an what amp fuse do i need or do i need to make seprate switch for all the lights i jus wanted them too all come on at once please let us know i saw the way u added the fuse thought at least next time the fuse an blow like u said u can cause a fire other way also its been fine for months it was yesterday this happend is this normal to u like it happend after all this time

[@PhillipsVision]

Vlogstar Parm led strip lighting is usually about 2 amps. If that is your case then 20 gauge should be sufficient. I personally would go with 18 just to play it safe. Never hurts to go heavier for precaution

[@parmindersidhu9690]

@@PhillipsVision hi ok whats 20gauge is that the wire as im using speaker wire but high quality init

[@PhillipsVision]

Vlogstar Parm speaker wire is normally 24 gauge and not well insulated. The higher the gauge the thinner the wire. I wouldn’t recommend it

[@pacman2460]

I’m confused so How would I do this for a remote wire that is connect to my amplifier to turn on/off using a toggle switch?

[@PhillipsVision]

Pac Man is this for a car amp? Are you using it as a boost?

[@pacman2460]

Phillips Vision yes it’s for my car amp. I wanted to install a toggle switch to turn it on/off whenever I don’t want the subwoofer on. So it has a remote terminal on the amp but I don’t know how i can connect the remote to the toggle switch to make it function. Like how would I connect it all together with the inline fuse? Thanks

[@pacman2460]

Phillips Vision please any information will help Thanks in advance

[@PhillipsVision]

Pac Man it should be pretty much the same setup. I’m not a car stereo guy but would think it’s the same. The toggle is basically connecting/disconnecting the power from the device, in your case the amp. You should have 12v going to the amp, running through a fuse and the toggle. Next, ground your amp on the chassis.

[@pacman2460]

Phillips Vision so on a two prong switch, I connect one wire which is the power(the remote wire) and the other wire is the ground?

[@LANDSHARK97]

will this method work with LED headlights??

[@PhillipsVision]

I would recommend wiring the led headlights directly to the existing headlight switch since that is already wired and fused

[@LANDSHARK97]

@@PhillipsVision my problem is my headlights aren't turning on no matter what I do that's why I wanted to directly put it to the battery nothing's wrong with the lights either I just bought them

[@PhillipsVision]

@@LANDSHARK97 have you checked the headlight fuse and relay? If nothing else works, yes, you can wire them to a toggle switch through an in-line fuse.

[@LANDSHARK97]

@@PhillipsVision yes i checked the relay and it's good
