This seems to be a chronic problem with these cars. Here's what's going on. Have a new painless wiring harness, new steering column and turn switch harness. All fuses are good, new flasher. Headlights on I have tail lights, parking lights I have tail lights. Step on the brake no stop lights, Ign. switch on no directionals. I have the instrument panel disconnected. New 1157 bulbs. Does the instrument panel need to be connected to the harness for things to work? NEED SOME SERIOUS HELP!!
