What I did was bought everything BUT the fog lights and used my own lights. So now the inside will look OEM.

In your case, does hardware only suffice or ECU/BCM modification done to sync fog lamp with headlight for OEM functioning.

Greg, This is undoubtably the most detailed and beautiful description of an installation that I have seen. THANK YOU for being a member on this site!

Now on to the wiring harness, the ground points are again a 10mm bolt head, the fog light ground must go under the other connecter or it will not allow the bolt to go back through the eyelets. I used

And here is the last part. Before starting I suggest you get something to fight corrosion, none of the ground points or battery terminals have any corrosion protection on them: You'll need this as

I still have to modify my BCM to recognize that I have fogs there. BUT I have an al OEM look which I like.

Hi Greg, I understand this is done long back, but if you can recall and tell me if the harness you have mentioned was from fog lamp relay to fog lamps OR anything from fog/light stalk to relay box? I mean if it was just piece to piece replacement at steering end or you had modified the harness as well?

I haven't started this mod since got stuck at this particular thing for while during getting schematic layout finalization.☹️

So fog works but not glow indicator on console with bcm modification?

I had Chevy reprogram my BCM but no fogs as of yet so i have to recheck all my connections.

The OE harness connects to the fog light then to the fuse box. The stalk replacement is just a matter of switching one out with another.

Anyone tried fog lights installation via wheel well, I mean by removing plasric lining from wheel area to acceas fog lamp assembly?

Its much easier to pull the bumper.

 

Hope all this helps!

Thanks Adam for your valuable inputs. :)

 On the harness part from stalk end, I understood that the existing harness have the required wires, just stalk need replacement, am I correct on that?

Yep just the stalk, that the only thing you'll do inside the car.

 

Anytime, don't hesitate to ask!

Hi Adam,

 

Finally I got the things in line. Got GM parts and installed those till relay. Good part, no requirement of BCM modification. Just after installing relay and fuse system recognises fog ON. Ordered Hella 60mm halogen projector fog lamp low beam but received high beam. Little confused if to keep them or ask for replacement. My doubt, if I install high beam fog lamp, will they blind oncoming traffic, though these are mounted low?

Adjust them lower if it is aimed too high. Those are made to be mounted higher as a motorcycle headlamp and not fog lamp so they may be low enough to not bother oncoming traffic.

Hi Mr. Tozzi, I already requested replacement with Amazon and received one piece but stuck with other one so have to wait till then. What I seen difference in high and low beam module that apart from having metal filter plate in low beam module, its reflector is oval shaped unlike round in high beam.

I thought its better to replace with low beam as after installing and then removing be a cumbersome job. Lets hope low beam will work as expected. Keeping my fingers crossed.

Let me know if the link works for you

Hi Adam, pics have helped me. Just a doubt, have you opened the relay box to plug the positive wire for supply?

I mean, after I installed the fuse and relay the system identified but when I checked I found that the supply is fed through fuse to the relay contact so using simple wire tap is not going to work. Seems I need to open relay box and insert the wire to correct slot like Greg have mentioned.

 

One more thing what size wire you have used. As mine lamp uses 60w HB3 bulb so as per wire size calculator it came as 2.5 mm2 but on safer side I bought 4 mm2. Just need to check if this can't create problem at connector end.

Its really getting bad. :banghead:

 

I made everything ready, lamp mount, wire harness and boom!!! They have pre-installed wiring for fog lamp. Now, I can't use my harness with the connector in relay box since the existing wire is not coming out from its place. And can't use existing harness since wires are thinner than the headlights one (assuming 35w load they have mentioned in owner manual).

 

Two options, tap the existing wire and use a 40amp relay for driving 60w x 2 load with new harness I made. OR

Throw everything I bought and use GM fog lamp.

 

Can anyone suggest?????

 

Also, what type bulb they use with GM fog lamp?

Thanks Mr.Tozzi. I am thinking of same and will see if existing relay box have enough space to hide the big 40amp relay. Meanwhile, planning to install cheap 12$ lamp.

After searching net, seen some adaptor which can convert one bulb mount in other. I will see if I can get adaptor which can allow to is H11 bulb (factory setup, 35w) in HB3 lamp.

 

Update - Installed cheap lamps for interim solution. Results are good, will check how effective they are in next road trip. I will try to make a adaptor for fixing H8/H27 bulb in my projector. Till then, expecting the current lamps will hold good.
