The brake lights on my 87 camino (daily driver) stopped working...I checked/tested the fuse and it's not blown and I have voltage to the brake light switch plug..

Also have power to the l/blue and gray wires (coming out of the switch)when the switch is activated...

The switch itself, Has 2 seperate plugs to it ...one plug has 3 wires ,L/blue, red and L/grey and looks to be 16 gauge...The other plug has 2 wires (20-24 gauge?)..

The 3 wire plug as mentioned above I believe to be for the brake lights ...BUT can anybody tell me what the smaller gauge 2 wire plug is for ??? Could it be part of the problem ?

I did notice that the fuse for the brakes is also for the emergency flashers which work fine along with the turn signals ....JUST NO BRAKE LIGHTS !!!!

I am not good at the wiring stuff so Any sugestions would be greatly appreciated ...

I need to get her back on road . the 3/4 ton 4x is sucking me dry as a commuter rig ....THANKS , Kevin

Just a couple of thoughts. No diagrams with me so I'm guessing. Maybe someone with some real information will show up. I'm going to assume you have a cruise control system. That's probably why there are 2 plugs on the switch. I think the 2 wire connector is really the one for the brakes. If Chevy continued to use the same color code on the brake circuit, the 2 wire connector has an orange & white wire on it. The white runs from the brake switch to the long turn signal connector. If this assumption is correct, you should have 12 volts all the time on the orange. You should have 12 volts on the white as you push down the pedal.

Reading your original post, you say you have power into and out of the stop switch and 4 way lights and turn signals all work. That tells you all wiring and bulbs are OK. The stop lights share the same filiment in the bulb with the turn signals.

The stop lights run through the turn signal switch. This is how one light is able to flash the turn signal while you have a stop light on other side of the car. The turn signal switch is bad.

Just a touch more information. The El Camino Store shows the same turn signal switch from 69 to 87 (See attached link). Assuming they have the correct information, the brake input wire is white. When pressing down on the brake you should have 12 volts on the turn signal connector white wire. The brake outputs, from the turn signal connector are green and yellow. As Old Longboarder pointed out, leave the turn signal in the off position. You should have power on both the green and yellow. http://www.elcaminostore.com/catalog-pages/06group.htm#turnsignal

Hey guy's,

I found the problem !!!!
with your input about the turn signal being part of the brake light wiring path .. I traced the wires and found that (of all things!!) the wiring harness coming down the column to a wide "connector plug" was were the problem was...
The connector plug had come loose !!!!
I pushed it back in and presto !! , Brake lights . How that plug came loose ,I dont know...
THANKS GUYS !! Your input saved me a lot of frustration .
