68 RS, No Brake Lights, All other lights work, Switch is good.

I assume this car has the wiring correct configuration.

This is what I know/have:

A) Rear turn signals left and right on all four lights.
B) Rear tail lights Left and Right on all four lights.
C) Tag light.
D) Rear emergency flashers left and right (although very very fast).
E) Reverse lights Left and Right (lower panel of course).
F) Front turn signals left and right.
G) Front running/parking lights left and right.
H) Front turn signals left and right.
I) Front emergency flashers left and right (although very very fast).
J) 12 volts going in the brake light switch.
K) When depress, 12 volts leaving the brake light switch.

I HAVE used the search function but cannot find my unique problem discussed. Not saying it's not there, just didn't see it.

Any clues? I want to drive to the big nostalgia cruise in/street drags at Atlanta Motor Speedway this weekend and the brake lights are preventing this.

Thanks guys!

Prepare to be the center of attention when you drive a first generation Camaro. You will be gawked at. Grown men & women will coo like children when you drive past. Children will scream like babies. Dogs & cats will get along. Does it get any better?

Re: 68 RS, No Brake Lights, All other lights work, Switch is good.

Let me continue where I left off. I went back out and done more checking.

I have tried getting brake lights with:

L) Turn signal left turned on.
M) Turn signal right turned on.
N) Parking lights turned on
O) Headlights on low beam
P) Headlights on high beam
Q) Emergency flashers turned on

Other facts:

R) They were working fine two weeks ago (road side safety stop)
S) Sometime in two weeks they malfunctioned (pulled over last night night)
T) Wire with 12 volt power going in to brake witch is orange.
U) Wire powered with 12 volts out with pedal depressed with power is green.
V) I have the Detroit Speed Electric headlight conversion but have had no issues in over a year.
W) I changed the dimmer switch two days ago, the high beams would not come on but have removed and replaced it again checking all wires, all is well.
X) Running out of alphabet!

Have you checked for voltage at the brake/tail-light housing? Is the brake light and tail light the same socket? Checked ground at brake light socket?

Stupid questions but I didn't see that in your alphabet soup.

A 68 wiring diagram I have shows a 14 gauge White wire coming from the stop switch.

Re: 68 RS, No Brake Lights, All other lights work, Switch is good.

I don't know if this applies to your car, but I had similar annoying little issues with my ss/rs. After checking and cleaning ALL the exterior sockets, I found the rear taillight sockets to be worn loose from age. I ordered all four rear tail light sockets from (maybe American Wire) the internet and the rear bulbs now snap into the socket. Big difference! I did find some corrosion in about half the exterior sockets. You may want to check them all.

Also, brake lights have their own fuse. But if you say that youve got power to the switch, I guess its good. I think it goes to the turn signal switch after the brake light switch, to control the blinker action when you have the brakes applied. Maybe that rounded harmonica connector on the column needs cleaning? I think the blinker, hazard,brakes use the same wire all the way back to the sockets so I think your problem is under the dash/steering column somewhere.

I think this is it! The brake light circuit does go thru the T/S switch to control brake light function when turning. It's common to lose brake lights with a bad T/S switch. Power should follow (white) wire to T/S sw then return out the same wires as T/S signal (yellow and Green?)

I would check all the connections in that big rounded connector first. And look for a broken wire while youre under there too.

Found three wires pulled back from that connector along the steering column. Only thing I can figure is when friend helping me with the brake bleeding had these dang over sized combat...what ever the hell you call them boots on must have snagged it. Dunno.....

Anyhow, THANKS GUYS, all my lights work now. Horn..... another story, it quit too!
