Electrical Headlights Turn On When I Press the Brakes

Tomorrow is hopefully the day I can get this electrical stuff on my 76 CJ7 fixed. 3-PO's ago installed a Painless Wiring Kit and there really isn't a whole lot of spliced wires going everywhere and are a couple things I need to get sorted out.

-Headlights come on when I press the break pedal
-None of the blinkers are working
-Both blinkers on the speedo light up when I press the brakes

I want to get this road worthy before the summer and I need these to work properly. I have replaced the blinker and hazard plug hoping that would be an easy fix (got that info from reading a bunch of threads). I think I will start with the break switch and start checking where the grounds are located. I have all the tools ready to go I just need my back to hang in there. I do have all MSD distributor and MSD TB AMC 401 and it all works fine. Does anyone else have any other suggestions on where to go? Everything works on the Jeep except the gas tank leaks and I have a 21 gallon tank showing up next week.

I'd appreciate any other things to check out. Thank You!

Some times when there is a bad ground at the bulb it will feed back through the dash indicators. Make sure the stop light grounds are good. Good luck.

I agree with a ground issue. run a temporary ground from the tail light housings to the battery and see if that fixes it.

I Messed around with a circuit test light and I slowly frustrated myself. Electrical isn't my thing but I'm learning at a slow rate. I will try grounding the rear tailight and grill, I was also thinking about grounding the grill. I'll checkin tomorrow. Thank you guys!
