My lightbar arrived yesterday. I did a mock install this morning to check the fitment with the brackets i had ordered and i had the wire on passenger side which seemed to look right.....but after researching the wiring threads i noticed most show it on drivers side. There were a few that also showed it on the passenger side so got me wondering is one side better, does it matter? Pros/cons? The shape (curve) of the back of the light is slightly different depending on which side is up so I wonder if this affects wind noise? Im getting my brackets powdercoated so i have some time before I'll be wiring it up.

I installed mine on the passenger side... it just seemed to fit. I will soon be removing it though as the wind noise just seems to be too much.

The lightbar is gone and I went with 7" LED Round lights on the bumper and A-pillar... it's amazing how quiet it has gotten.

Remove the 2 bolts near the wiper holding down the cowl. You can then left the cowl enough to pass the light bar wire down and into the engine bay from there. It's ok if a bit of the wire is left exposed after you bolt the cowl back down.

This guy does a pretty good job of detailing his light bar install:

I haven't wired mine up yet. I hope to go pick up the light brackets from the powdercoater by the weekend if I get time. I think I'm going with the passenger side also. Thanks for the tip on running the wire under the cowl.

Go to Home depot and get some Frost King Kerf Door weather stripping, the white part plugs right into the back of the light bar and completely eliminates the noise. I use 2 strips. perfect solution for about $10 and isn't noticeable. I've had mine installed for about a year and a half, hasn't blown out yet.

so put it inside the heat sink lines right?

The white part just plugs into the cooling veins on the back. It interrupts the air flow and stops the crazy noise.

For the plain rectagle style you can install it either ends but most of the wires come out on the left side of the lower bar so for the most part is installed with wires coming down the passenger side. I have an aerodynamic designed bar but still had a bit of noise but I ended up using white duct tape to match the light bar color until I find a comparable better solution. I have hardly any noticeable noise from the light bars. Between having and not having the light bars was hardly a difference. I have done many comparisons with light bars. If you get a nice set of 20" light bars and put it on the hood, it's more than enough light output. Honestly I hardly ever need the use of the 50" bar. The 20" does the job. If I wasn't in the business selling led light bars, I wouldn't have installed the top bar for two reasons, noise you have to filter and it's more light than you really need. Look at my setup, it's overkill but I can use what I need but at the same time I was able to test and compare.

Because I ran my light bar to an sPOD, I ran the wires down the drivers side. I don't think it really matters though because your harness, if you chose to use one, will have power wires running to the battery and wires running inside the cab on the drivers side. Using a harness will probably be easier by running the tag end on the battery side like previously mentioned.

With my light bar, i didn't have the whistling issue, I contribute that to the mount i picked and how it orients the light above the windshield. What I do get from time to time is roof cavitation at highway speeds. The solution to that is simple, crack your window to pressurize the cab. :) 60 MPH or less I get no cavitation.
