Well I switched all the bulbs back to regular bulbs and everything works fine. If I put in one led bulb in the place of a 1157 bulb everything flashes unless you turn the parking lights or headlights on. I have decided to forget the led and stick with the standard bubs.
I know this has been covered but I started by replacing all the wiring harnesses on a 70 Challenger and changing over to led bulbs in the dash and turning signals. I changed out the flashers to led compatible ones and put in a new dimmer switch on the floor and replaced the one in the dash also...
There is an emergency flasher around the steering column under the dash and the turning signal flasher should be in a bracket on the back of the ash tray. I was working on mine this weekend and that was where they were located.
I put in park and turn the key to shut it off and it stops short of being able to remove the key. It is a 70 Challenger key on the column, shifter on the floor.
