Step on the brake pedal and WTF...??

I hate electrical issues. No, make that HATE them!!

New project car (69 Dart), all STOCK wiring. Wiring harness is so virgin, the car's never had an aftermarket radio! Everything works good, except:

Step on the brake pedal and brake lights are on - good.

But...so is the front parking lights/singnals and turn signal indicators in the dash.

I swear! Also when I activate the turn single lever in either direction, BOTH front parking lights/singnals light up. Not blinking, solid illumination.

I thought I've seen it all, but nooooooooo. Where would you start to track down the issue??

Thanks!
