Park lights and dash lights turn on when pressing brake pedal

[Wcotner96]

Been working on my 70 RR and cleaned up the dash and got new bulbs in everywhere, headlight switch is new and all lights come on as supposed to,

Brake lights do not work when lights on/pedal pressed

Lights off/pedal pushed all park lights turn on

Gotta be a wire crossed possibly or bad ground? Any help would be greatly appreciated

Disconect rear/tail lights harness and check if park/cluster lights still comes on when pressing brake pedal.

tail lights not grounded or wrong bulb installed

I think you’ve got wires crossed. I suggest you pull off the driver’s kick panel. There’s a plug there that included the tail/brake lights. Start looking for melted wires/terminals there and cross check wires with a meter vs the wiring diagram

You make no mention of the turn signals or 4 way emergency flashers working? Do they work?

Hey, so right rear signals work, right rear hazards work, I unplugged the tail light harness and it does the same thing. So issue may be in the dash I imagine just not sure where to start

What? So the left side does not work? That is such a simple system.

all lights work when turning on with the switch, left signals do not work nor flash with hazard switch, right side turn signals work as do hazards on right. Brake lights do not work at all. Tail lights stay same brightness when braking

Take all the bulbs for the front and rear park and turn signals. Fix one at a time. My bets you have one rear socket messed up and possibly a bad turn signal switch.

What wire colors are arriving to the brake pedal switch prongs?

They should be pink and white… no matter which where. Pink from fuse box (“batt” throught a 20 amps fuse, so allways hot), white to TS.
