thanks

I'll get you some pics tomorrow. I do know that they are the purple and black wires that have a 2 prong female weatherpak connector.

Kamaros

When it come to Camaros; The Fog light wiring changed over the years.

From 85-87 the system was installed at the factory using an independent harness that ran along with the cruise harness ( if equipped ) and plugged into the dash harness over the drivers foot well.

Starting in 88 the Fog Light wiring was integrated into the dash harness and the wiring runs thru the C100 firewall connector. If an 88-92 got fog lights from the factory than the fog light wiring will be integrated into the engine harness. If there were no factory fog lights - than the engine harness is missing these wires and plugs.

Here's a C100 diagram from an 89 Camaro so you can locate the Fog Light wires on the dash harness side of the firewall. ( A1, C2 & C3 )



Hope this helps !

Just some info from Jim85IROC that I thought was interesting:

From 86-on, your fog lights would work with your parking lights on and when your low beams are on. As you learned, they won't work with high beams.

BUT... in 85, in addition to many other one-year-only peculiarities, the fog lights would come on ONLY with the low beams. With just your parking lamps on, the fog lights will not come on.

Ok, so I got both harness types. The independant that has a rubber type grommet that I am assuming needs to go throught the firewall which means I would have to make a hole to it.

The two connectors that go into the firewall are the one that goes to the switch and then the one that supplies that constant power to it. It is a single red wire with a white weather pack which does not fit into the power block above the kick panel where all the other power connections go. But it does not fit. Nor it fits at the fuse panel either. Any suggestions?

My 86 fog lights only work in Parking light mode and or low beam mode. But not in high beam mode. You can easily bypass the relay and have them work with high beams. I left mine in its factory specs.

Check under / around the steering colum at the firewall for a single red wire and plug. ( I can't recall - but I think the plug is gray. ) There should be a single red wire from the 'main' dash harness feeding the red wire on the fog light harness. ( It might be taped over on the dash harness ) If your car is an 87 than it should be there somewhere !

Thanks for the info. I'll get back under there and look for it. At least now I know what to search for.

ahhh this all makes sense now i have the wrong harness thanks for the info. so then on the 88 and up is the relay for it above the wheel well

itsMikey

i just took the stock ones out and put in pilots and butt connected the wires

Well my car doesn't have that wire or any wire taped under the steering column. Five bucks my car has an 88' type harness since it was built mid way through the 87' model year. Time for some creative electrial work.

I would just run fresh new wires and reuse the factory switch and a relay.And if you choose..you can connect the relay to the parking lights aswell and even have the highbeams turn the foglights off.Its a very simple wiring schematic to do instead of fishing for the factory wires that are pretty old now.It wouldnt take longer than an hr to do start to finish to wire the foglights this way.

see what i did is i cut the purple wire that comes from the switch to the fire wall and just put a new wire all the way to the lights. i bypassed the firewall connection and in doing that i dont have the relay. so the factory switch works and all but it eats away at my power big time. i dont know how to wire up a relay or else i would have already

86White_T/A305

ahh i see well there is a simple way to fix this and not burn up that wire using th foglights over a period of time.buy a relay and a harness for a relay and here is what you will do.

the relay will have 5 wires on it..each a different color,red,white,black,blue and yellow.

under the hood find the same purple wire that is powering the foglights now and cut it back in half first.

wire the relay as follows

yellow wire connect this straight to the battery with atleast a 10amp fuse.

white wire will connect to the purple wire that is coming from the foglight switch

the blue wire will connect to the other half of the purple wire going to the foglights directly(which is the power wire of the lights) ..you can run a thicker guage wire to each foglight from here which i do recommend aswell

the black wire connect it to ground..and if you can..run new thicker ground wire to each foglight to the battery even for less of a power draw to the rest of the car.

this will provide you sufficient power to the lights without draining the life of the foglight switch that is already sharing power from other things and stop it from burning up they should be brighter after this aswell.enjoy

What I was thinking of doing, is the red power wire from the fog lights that I cannot find the connection for it cutting that white connector off, using an extra power seat wire connector and splicing them together. Then that way I can plug it into the electrical junction box where the power seat and other power items are hooked up to. Hopefully that does it. I may have to compare the wire size before doing so of course. The switch wires and harness connector is ok and hooks up right.

MY87LT:

If your car has a power junction box behind the kick panel - It's not an 88 harness. That junction box was not used in the 88 & up cars. Here is a picture of the Fog Light wire breakout from the main dash harness:



It's the red wire with grey plug and breaks out of the main harness above the brake pedal switches. (Sorry I couldn't get a better pic !) This pic was taken in one of my 86 IROCs.

Your idea to splice it into the junction box is a good one. I would connect it to the "switched" power side ( Pink ) of the box rather than the "hot" side ( Orange ) - but that's me. I only posted the pic for Ya' so that you can see where it is and because cutting/splicing is ALWAYS better avoided if possible.

Visual aids are always helpful. I'll try to look for this wire now that I can see what I am looking for. Thanks.

yea that does help a lot and it helps that i have an 89 so that means that the red wire does nothing for me lol. i looked and i have a brown i think it is that goes to the wire box on the firewall. the connector in the engine bay does not have the fog light wiring in it so that means that the wiring harness came from a different car. so that means i need to buy a relay and just wire it in to the wiring i already made. wow its nice to have this web site with out it i would be lost thanks everyone

Oh yea. Thanks to this site, I have save countless of hours, saved money on repairs and made new friends. And learned A LOT about third gen f bodies.

Well no luck on finding a gray wire as you said as my car didn't have it. But this is what I did:

Started from the front of the car and plugged in both lights.

Then hooked up the fog light relay to the fender where it goes and connected the green and brown plug to its socket by the steering column.

Bought a special drill bit that looks like a top toy, (can't think of the name) and made a hole under my light harness box.

Ran the fog light wires through the hole and secured the rubber grommet to the firewall.

Hooked up the fog light switch wiring and then spliced the red power wire into an empty slot on the accessory power junction box.

Fog lights worked perfectly. On with parking lights only, only with low beams, and then automatically turned off when I hit the high beams.

So pretty happy with the results.

thats almost what i did with mine. i used an 87 wiring harness and just cut out the fog light wires looked at the wiring diagram for it, found the wires and hooked everything up. everything works just like it should with the relay working too and wow what a difference in power draw
