THANK YOU! I've been looking for instructions on how to wire my lightbar up for a week. There are videos out there, but yours is the only one that's said anything about where to put the positive cable for the relay! Is it fairly obvious, sure. But messing with anything electrical in the past, I've learned not to do anything you aren't sure of, even if it makes the most sense. Once, I fried 3 alternators on a 240 Redblock because I was chasing an electrical issue without knowing what I was doing. Somehow, I ended up overcharging the system and frying 3 alternators. I finally gave up and took it in where the nice 70 y/o mechanic chewed me out for touching things I didn't fully understand. He mentioned that the one thing to never do was mess with electrical systems unless I was absolutely certain of the outcome. I never cared for his attitude. However, looking back, he wasn't exactly wrong. You've saved me a trip to an installer. Thanks!

[@williambtm1]

Thank you for your aid in explaining what goes where. I just had the auto elec install my new LED light bar, previously I had a set of excellent long distance driving lights installed by another person (who did not connect the in-cabin on/off switch, why I do not know.) My intention was to have both the LED and the long distance driving lights fitted to the front of my Subaru Forester with each set of lights controlled by each fully functional in-cabin on/off switch. However, the dude did not refit my spot driving lights telling me I won't need them anymore! So now by watching your presentation, I will be better able to return my spot driving lights (including the correctly set wiring and etc under the bonnet) to the front metal support plate of my car. Why, one might ask, well I live 100KMS from the city shopping centre and do a lot of night driving where wildlife is forever wanting to cross the 100 KPH highway. The road at that time of night is mostly bare of other vehicles I do not want to hurt any critters, nor do I want to sustain any vehicle damage. I reduce my speed when I enter the thickly forested section by 15 KPH or say 10 MPH, this provides me with a little extra time to react, either to brake firmly and safely, or choose to carefully take a measured veer around any on-road critter. My Spot driving lights are directed toward the grass verges of the roadway in order to watch for any and all critters. Also, 'all of that extra light' gives a greater amount of visibility during my night driving, thus provides more visibility control of whatever may lay up ahead of me along the roadway. Thanks for your advices.

[@lovegodessmls28]

I spent 12 hours installing my 2 lights along with the harness. my lights are 4 inches each.... what a simple set up but what a difficult execution. I had to really work hard in order to make it look like my lights weren't connected to anything (make it look clean). they're awesome but this was an extremely time consuming little project. It was well worth it.

[@dimoskadoglou1503]

Hello, awesome video! I ve been wanting to do this on our regular small city car but I m too scared it will interfere with the cooling of the engine. Did you notice any raises in temperature since you installed it? I m thinking of doing one of the 20inch one row led bars maybe that will help with more air coming in...

Im trying to install my light bar with a switch but it did not turn on. Im just learning about wiring. So on the wires themselves I did not put all the females on one side. For example on the negative wire from the light bar I attached the male connector but on the positive wire from the light bar I used a female connector. Does it matter if both male connectors are not on the same side of the accessory

The red wire of the harness is now connected too or rather tapped to one of the car wire that is connected to my dim light on the car.

Run it to the battery as the alternator also runs to the battery fad the alternator is the battery charger and hold power only the wire itself.

[@dashcamdude6690]

Could i use a piggy back fuse from high beam fuse to make them come on would that work do u know

[@squeakytaco2034]

I would not as you should really want to match the fuse to the light bar. Plus turning both high beams and light bar would blow it out. Using the correct gauge wire and fuzes is pretty important in terms of safety and fire hazards

[@gildarkplays7758]

Where did you connect the positive and negative wire on the switch

[@curtisporter5643]

Doesn’t matter, switches only serve as a way to break the circuit, positive and negative is irrelevant

[@1Martyn1]

All your hot wires should run to the battery or a circuit to the battery. All grounds can be ran directly to the chasis

Is connecting the red wire to the positive battery terminal always lead to draining the battery or does tht only happen to certain vehicles...bc I have a 2002 toyota 4runner, thanks!

[@DIYautotech]

No, so long as the circuit is not grounded while while the key is out of the ignition, the unit will not be pulling power. There will always be a bias voltage on the power wire, but no current is flowing through the unit.

[@israelrodriguez6986]

DIYautotech : so I have to have the key in the ignition while im connecting the red wire to the positive terminal and black wire to ground??? Trying to understand...

[@m240b9]

Israel Rodriguez he's just another KZbinr trying to be special trying to make a name for himself who doesnt really know much

[@mackenziepeek9317]

Israel Rodriguez if you run it to a relay with a switch it won't draw power till you turn on your vehicle. The only time it will drain the battery is if you run the light bar straight to the battery. With the switch you might experience a small phantom drain but nothing to kill the battery unless you leave the vehicle sitting for a long time without starting it allowing the alternator to charge the battery

[@HeetJoshiofficial]

@@mackenziepeek9317The switch red and black wire doesn't have a relay, that means the led in the switch will stay on all the time. wont that kill the battery? also can i operate the switch without attaching the red and black wires of the switch?

Hi there want to wire a light bar to my bus can I simply use a seperate on off switch to isolate it it's a road legal type led can I simply tap in my headlight wires instead of using seperate relays

[@rockyloccgarage2040]

Use a circuit like the headlights to trigger the relays, Then you wire in the hot side on the relay for the light bars own circut. That way the lightbar isnot pulling power away from the headlights,

[@1Martyn1]

The vehicles circuit isn’t just one specific item. It has a bunch of hots that leads to the fuses and to the switch for that fuse. Run it to a fuse that can handle the light bar power and beer tad bigger fuses other that what the manufacturer says. When adding something that’s not made for a vehicle it’s always good to create a new circuit.

[@rockyloccgarage2040]

You should use the cargo light as a relay trigger, say for instance you drilled the light bar on top of the roof, so that your cargo light is still perfectly intac. You can wire that relay low voltage side to the harness, so that way it triggers the hi voltage side on the harness which has its own big supplemental wiring and fuze, so that way the cargo light will shine bright and the led light will shine bright as well because its wired correctly.

[@NorthFenFarm]

Luis Espinal instead of connecting the red power wire to the battery you need to connect it to a wire that is only live when the engine is on such as your ignition switch (you'll need a multimeter to find the correct wire)

[@mackenziepeek9317]

Luis Espinal you can make a joint on the wires for you lights or preferably fog lights if you have them so it pulls power through the same fuze as your lights and will only come on when your lights are turned on

[@mattiewalker8858]

You make a good video, but the guiding to people that you can make a hazardous connection or short-circuit from a negative terminal to the chassis(ground) is not possible. Gloves or tape won't help either way. The negative terminal IS connected straight to the chassis. To have an accidental short of any kind, you must have a complete connection from a power source, (the battery - from both terminals, positive and negative) or from another power source that has both leads channeling through the car's wiring system in some form or fashion, then make a COMPLETE CONNECTED circuit. Which without a load(light bulb, light bar, radio, etc...) to use the power, results in a short-circuit. Other than that, your video works well enough. Have fun and good luck in your quest for knowledge.

[@DIYautotech]

The wrapped glove trick is meant to be used so that the negative cable doesn't come back into contact with the negative terminal of the battery causing the arc. Not meant for stopping contact with other parts of the vehicle. I understand electrical theory and practice, and use it daily, but if you were a content creator, you'd realize that after filming a segment multiple times (as is normal for most) you begin to say things that are not true to spec....Sometimes these things don't get caught in post production etc. You get the idea. The point being, these videos are not peer reviewed step by step productions. There are a "guide" for which many can build a foundation on. Thanks for your input.
