Bad Ground?
 

I have a 68 Camaro that when I press brake pedal (l) front parking light comes on along with bake lights and the turn signal light in the instrument cluster. I rewired the car with AAW kit and everything has been working fine. This just started recently. I checked the grounds and all are tight. Any suggestions on where to go next? Would a loose wire in the parking lamp socket cause this?
About a year ago the turn signal switch/hazzard switch was replaced.
this problem just started recently. Any suggestions?
Thanks

I had a similar type problem when I rewired my car (also used AAW). I had a bulb sending "feedback" (or what ever it is called) that was cause the the marker lights and turn signal lights to flash when the turn signal was selected. I was trying to use some Ebay LEDs in the turn signal housing in the grill. I started pulling one light at a time and when I pulled those Ebay LEDs, the problem went away. Replace them with normal OEM type bulbs and the problem went away. I would try that first. Hope you find it.

Thanks for the tip. I'm running standard lamps and checked to make sure the correct lamp is in there.

Very difficult to diagnose over the net, but I'd start with the brake light lamp, on the same side that your turn signal and dash light is illuminating. Sounds like the lamp (bulb) is shorting out in the socket, or possibly internally, when you press the brakes, causing the back feed to illuminate the turn signal, and dash light. Doesn't sound like a ground issue, but again, tough to diagnose over the web.
This happened to me before, and I had a bad brake light lamp. It was a dual element, and shorting out internally, meaning one filament had failed, and was touching the other filament. Changed the lamp, and fixed the issue.

Thanks Scott. Yes I agree hard to diagnose from a keyboard, I'll keep at it.
