 What is happening guys? Thanks for stopping back by the channel today right here with the rust belt mechanic We are going to be doing something just a little bit nice fun and easy today on the Duramax Yep, got the Duramax going again, and what we're going to be paying attention to is a little bit more Lighting you have a look at her. We're going to be doing a light bar I picked up one on Amazon deal really good deal this last week ended up getting a 32 inch light bar which by my calculation And looking at the front of the Duramax will fit just nicely built behind the grill. It'll fit It'll provide a bunch of light. I don't know. Let's crack into it and see how it goes So the light bar ended up getting was from auto-tune just on Amazon. It's a cheaper light bar It's just something that everybody's going to be able to do it ended up being like 48 bucks So something really simple easy it came with a 32 inch light bar everything it takes to mount it and The harness that it comes with also for hooking everything up that you need You will have to do a little bit of extra bracket making to make it work on your Duramax or your Chevy truck But I'm going to show you what I'm going to do with it at least a you know make it work for me so what I got Was this here this auto-tune? 32 inch light bar does enough for spot and spread on the light. It's going to look really good It's going to give us a lot of extra light It's going to complement all those extra LEDs that I put on the truck For making an extra bright going down trails and down some of my buddies Driveways in the middle of the night. It's going to look really awesome But the first thing I want to do is I want to take care of that nasty Looking a bracket that's behind the grill that just sticks out because it's never painted So we're going to paint that first then we'll get the light bar put on So I've got some Rustoleum universal paint and primer black That's what I got sitting around the garage. So that's what's going to make it look good So now that we got our bracket all painted up. It looks good. You know, it looks a lot better than the Uncoated metal material. So now what we're going to have to do is we're going to have to get something that goes all the way across Here that we can mount our light bracket to we want it to sit about an inch to two inches Above this Bracket here that goes across so we're going to need to make something that goes 32 inches out Right about in this area and I found something in my garage I found an old piece of plexiglass So I'm going to end up using that because it's easier to work with it's still stiff. It's still rigid I know a lot of guys is going to bang on me for you know, not using steel or aluminum piece or whatever But it's what I have available and that's what I'm going to use So here is the piece of plexiglass I'm going to be using it is three quarters of an inch thick So it's thick heavy-duty It's going to be able to hold what I need to and I'm going to get some self-tappers So be able to put a couple in each side on this part of the bracket and then my light bar is going to fit Right there like that, which will give a good spacing still give me plenty of air flow through to my radiator and my condenser and Give me the light that I really want so for reference here This piece of plexiglass I cut it exactly 32 inches long it'll fit nice with the brackets that I have I Spaced it up from this bracket with a 2x4 So that's how much spacing and then here from the ends. I went four and a half inches Out from the end of this bracket on both sides that leaves it perfectly centered and Perfectly spaced high enough to go through the middle part of the lower valence of our grill So we're going to pre-drill a couple of holes in through here To get where we need to go There we go a pair of each of those to hold it in so we'll get that screen in place here real quick since I've already Planned on running my wiring on this side of the truck. That's where we are going to put Everything else put it the wiring here. There we are Nice and sturdy. It looks like that's gonna set on there just perfect So one thing that I definitely don't see often enough is people Explaining how and why these lights and the electrical systems work how they work So I'm going to explain to you guys again This is the harness that comes with this light bar and you need to hook it up how they say And I'm going to explain how and why that is do you have to use a relay a Nice ground a switch power fuse and then your output to your light I'm going to show you here on this relay how a relay circuit works So on these relays and every single relay we'll get it to focus here There are four main pins. There is a 30 and 87 those are your main power relays or plugs to the relay and then there's an 85 and 86 portion So how a relay works is it uses a small current circuit to control a large current circuit? So on your 85 and 86 circuit, we will start with that first That is what goes to your switch the switch that's inside of your vehicle You will get power that comes into the vehicle through the switch and then out to a ground source That will you turn that one on and off and that will actuate the control part of the circuit And then you have the power side You have power and ground on there power goes to 12 volt straight battery because you don't want the straight battery feed of how many amps are going through this Going straight through your switch that will melt switches if you just put a switch directly in line with a lot of these bigger light bars It just won't work. That's how you melt down your truck You have your power circuit then going out to your main source the power and ground of that So your small circuit of your switch Turns on the relay which turns on the power that you have plugged into power and go the ground goes to your Main source so these harnesses make it very easy They do it as a dummy proof thing hook up these two to your light bar This one goes to ground This one goes to power and your switch goes inside your truck They make it easy and stupid proof as long as you do it that way But hopefully that gave you a little bit more insight of how these work and why they work why they need to so Right here is the wires and I already actually had a when I purchased this truck I had a light bar above the roof which that cab light bar is just a dumbest idea They make way too much noise So I have a wiring harness already sitting here ready to go So when you put these on here, that's another one of the biggest pet peeves is people don't use the correct things You can either solder these or get a good set of weatherproof crimps These butt connectors you're able to crimp these together Make them nice and easy there And then they have heat shrink to them as well, which will make these weatherproof I see so many guys using these freaking Household twist ties to put these things together and they wonder why did my wiring of my light bar fail after like six months? Well, that's why you big dummy The very last thing that you big dummies need to do Is zip tie your chit out of the way That's a big big pet peeve of mine And seeing these guys that had these hapaz or wires that are just hanging out in the middle of nowhere Or worse yet, you know where your hood goes up and down or in a fan belt or something stupid Take the extra time Zip tie your harness So it hugs other harnesses and is out of the way of all other stuff Spend the extra dollar and 95 cents on some hyper tough Frickin zip ties and do the shit right That way you won't have more headaches down the road Let's get this thing all lit up and see how bright we are Where do you get these things turning? Oh, it's got it. Look how's that look? That is gonna get us down the road nicely. I think that project turned out really cool It was really easy really cheap something that everybody can do for their Chevy or Duramax truck That's for sure One thing that I just want to make sure that you take away from this is do it right and do it right the first time Save yourself headaches down the road even though you guys are doing a cheap easy quick mod Do it right and it's gonna be awesome. That's for sure One other thing I wanted to point out was the awesome shirt that I'm wearing today Duramax life t-shirt they are for sale over at truck masters channel I'll put the link in the description down below. He's got some of those left He also has Duramax life badges the emblems that you guys can put on the back glass of your truck like I have before So make sure you go and check those out Thanks again for tuning in today guys.
