Third gen factory Z28 fog lights
Question. Are there any physical difference from factory 1985-1989
Fog lights then from 1991-1992 Fog lights? Are the mounting brackets any different? Also, when placing fogs on a non original equiped Z, what all is required? I assume the lights, brackets, switch, wiring, and bulbs.
Are the metal ports surrounding the lights required as I noticed some of the ports look different depending on the year model?

Re: Third gen factory Z28 fog lights
How odd... I have a 89RS, just picked up a pair of fog lights last Thursday, and have the EXACT same question.
oh yeah, and I'm From Mesquite... strange......

Re: Third gen factory Z28 fog lights
In the catalog it shows you purchased a 91-92 grill...
Im hoping the only physical difference is the camaro vs bowtie emblem...
maybe someone will chime in hear and help us with the fog lights.

I found a set that go to the 91-92...Not sure if they are the same as the earlier years though.

Re: Third gen factory Z28 fog lights
i noticed that too, which is why I said IF it works. If not, I didn't over pay for it, so I bet I can sell it. I like that it comes with that removeable plate holder.
come on over! gotta represent 75149!

Re: Third gen factory Z28 fog lights
The grills in question are interchangeable. The Camaro GM part number is 14081332; the bowtie 10139545.
From the following site: http://www.gmpartsdirect.com/index.c...TOKEN=43475709
The first is $51.58, the second $56.89. Shipping is high, but you'd still come off cheaper in the end, I'd suspect.

Re: Third gen factory Z28 fog lights
The same. The RH fog I purchased for my 85 IROC has the same GM part number as the 91:
Lamp, Fog R-H 5974580
Lamp, Fog L-H 5974579
BTW, in the ebay sale, though the ad mentions 82-92, the grill will only fit 85+.

Re: Third gen factory Z28 fog lights
Thanks James.
One more question. Do you happen to know if the fog light lenses are a replaceable part?
I bought a set of fogs from a member here and both the lens on each are cracked.
Really sux!

Re: Third gen factory Z28 fog lights
Here it is installed....
It's not a direct fit, there are seveal screw holes that hold it to the brace behind the grill that are not on the brace on the RS.
There were enough that were there that it worked ok, but I had to use the licence plate holder to hold it in place. Not including the licence bracket, there's only two screws holding it one
If I want to later, I could make it work better, but I think it's ok now

yeah, I know, I got some work to do on the bumper

Re: Third gen factory Z28 fog lights
There is somthing about the stock fogs for our cars that I just hate... To me, they just seem to big and bulky for where they are mounted... I removed mine and went with a 4th gen style for a fraction of the cost...

Re: Third gen factory Z28 fog lights
Does anyone know what the voltage is suppose to be for 3rd Gen IROC foglights? I am getting 24 volts to mine and that doesn't seem correct!
Re: Third gen factory Z28 fog lights
24V is not right at all, either something is up with your meter giving you a false reading, or you have something going on with the car and I wouldn't run it like that. not good.

Re: Third gen factory Z28 fog lights
Yeah, if you're really at 24v, those fog lights will be the least of your concerns.

Re: Third gen factory Z28 fog lights
It is just the fog light circuit that reads 24v. Every other circuit is 12v. I was just making sure that I was correct in thinking that circuit wasn't suppose to have 24v. I can only assume that something is wrong with the switch or something else. I do have a couple problems with the wiring on the car. (As expected considering it has sat in a she most of it's life where squirrels and rats could mutilate the harness!)

Re: Third gen factory Z28 fog lights
I think the fog lights look cool like that. And don't worry about the bumper. Lol even I replaced the fog lights on my Trans Am and the bumper needs a lot of work.
