Questions & Answers

There is one for the old body style of the 2024 gmc sierra 2500?

Is 2024 the year of the General Motors Corporation? Would you mind clarifying which years you mean When was that? Unlike what you're used to, we do it differently.

Can it be installed on a 2001 GMC Yukon?

The low beams will not stay on with the high beams, but you can manually keep them from going off and on. Turning on your high beams turns off your low beams, as the system cuts the ground line so the ground is not visible to the low beams. On your low beam harness, you will find a yellow wire. need to do is crimp a ring terminal on the wire, tighten the ring terminal to a nearby bolt or screw, and use a ring terminal. In order to keep a constant ground between both headlights, you need to only do it for one light. My 2000 Tahoe is still going strong, thanks to what I did. i did this to my Honda a couple of years before I sold it, and it never had any issues.

I have a 2002 3500 dually 4x4 will this fit?

That should be the case. Connect the battery to a power source. However, in order to remove the main fuse box under the hood, you need to remove it completely. The ONLY thing you get is the circuit board. Drill and tap new threads. You will have to purchase new screws to hold this new board in place. It will be necessary to drill and tap new threads. Please, be extremely careful while drilling out rivets holding the circuit board.

What is the fit for a 2002 Avalanche?

That is not the case. For my fuse box, I bought a replacement fuse that did not line up.

This is an awesome product! Find out how to do the 4 hi mod on 99-02 by reading the review We have two trucks, 2002
5/5

It works great, it is the easiest way to modify the 03-06 jets with the 6-Hi mod It is an 07 truck. Those who want the 4 lights to come on during 999-999 All you need to do is tap into and ground the yellow wire behind your passenger's headlight to make it work. (nota bene It is not advisable to cut and ground the yellow wire. Make sure you use a t-shirt An alternative to tap is one that works in a similar way.

The installation process was simple and the product works as expected
5/5

The step-by-step method is for those who like it. I installed the product in a 2006 Chevy Silverado 2500HD LT Duramax. The Hood has been opened 2. Disconnect the positive battery lead from both batteries (for those with dual batteries and a diesel engine)*3. the cover from the fuse box under hood on the driver's side of the vehicle behind the battery*4. I removed the fuse needed for the Fleece Performance Engineering installation Angola - The 37
5 sign. The easiest way to install this product is via the installer Angola - Based on images provided on Amazon site for product number 6. There is a slight twist in the contact posts of the fuses. Fuse installation was done in the same manner as they were removed. Removed fuse box cover and reinstalled it. The battery cables are hooked The test has been passed. I installed them quickly and easily. They work as expected. According to their purpose, they worked.

I love it!! Thanks for your amazing work! When I found the site, I thought it might be worth the few bucks to give it a try
5/5

There was a much brighter light when you held on to the signal lever. I am floored! Spending twenty or so dollars on this was the best decision I ever made! The relays are easy to set up, but you don't want to switch them on and off often, as you will have Getting the bare circuit board back into place is easy! Just lay it down and plug it in! I love how the lights are shining on A long dark road leads me to my home, so I can SEE everything around me! The high beam starts all the lights, including the fog lights, but does not light up the running lights, since these would not identify anything in the dark The feeling of not seeing as well when you go back to the low beams is very dispiriting after a time of seeing It's when you switch to high beams that everything changes! Low beams and fog lights work just as they always have, it's only when you switch to.

There is more to it than that
5/5

Regularly, I make a trip of 90 miles through the Washington coastal range that is thick with mammoth elk and deer darting through the brush. This simple mod worked very well on my 2006 Silverado 2500, which had weak headlights at best. Instead of spending several hundred dollars on hid projector lights, it turned out to be an excellent alternative. Add some decent 9006 & 9008 to round out the package I was totally surprised at the transformation of my truck after installing the led modules. This was something I have been wanting to try for so long that I am only regretting waiting so long. Despite not having any tools, the installation took all of two minutes. There is no need for me to have factory fog lights, it's fine with me whether you have or don't. This is a highly recommended book. I was not compensated for this review and I was in no way affiliated with the product.

An excellent grade As soon as you get over the shock, you'll love this! It's the easiest and fastest upgrade to date for a Silverado LS 2500! With the help of the GM switch, relay, and harness, I installed fog lights
5/5

Maybe that is the reason for the way things are now) This information would have been more useful to me if I had read it more closely. had no idea when you select High beams that your fog lights would automatically turn on and you CANNOT turn them off. If you are using low beam, you can turn off the fog. Though I understand the level of control done over the lighting with this card, I simply thought there was more I could do with it. It's not that I'm complaining, but rather that I'm observing.

The modification is super outstanding
5/5

My only regret is that I could not have discovered this much earlier, when they first came out. For the past 12 years, I've owned my truck 15 years and have had it for at least that long It was possible to go high, but it would be done I spent the most time checking to make sure I had open on my phone one of the pics from the reviews on this page. The program can be installed in about 5 minutes. the hood, remove the plastic cover on the fuse box, pull out the relays, place the fleece thing over the relays (there may be fuses there, but I'm not an auto mechanic), test you lights, replace plastic cover, close the hood, and enjoy! We just drove around town through the hills, with a 6*HIGH setting for errands and lunch! It is a straight up good utility mod, definitely worth the money.

This product does what it is advertised to do
4/5

Would have been nice if the daytime running lights were also turned on. One thing I would like to see is that it would be possible to also turn Apart from that, it is as described, and the installation process was easy. Installation was not documented, but it was fairly straightforward once I realized where to install it.

An Easy Way to Do It All A Mod for the Headlights
4/5

I think this is one of the best $20 mods I've ever bought for my car. This program can be installed in no time at all. Take off the plastic cover on top of the fusebox. Four relays need to be removed. Simply drop the little circuit board into the slot. The relays need to be replaced. Put a new cover on the fusebox. This is done. There is no grounding, no soldering, and no tapping of wires under the My 2006 GMC Sierra 2500HD works just like it should after I installed the PCB. Now that all four headlights are on when you hit the brights switch, it's much easier to see. It was only because of the instructions that I didn't give it a 5 star rating. The location had to be checked online so I could make sure I was putting it exactly right.
