Brake lights not turning on ! Could be an easy fix ?
Another good wiring resource is
classiccarwiring.com color coded wiring diagrams.
Something that is not obvious but our cars have 2 flashers.
1 is for the emergency flashers and 1 is for the turn signals.
Sometimes when the turn signal connector is mated to its matching connector the terminals can push out enough to not make contact.
Also I have heard some aftermarket turn signal replacements have a wire color or 2 swapped.
So comparing your old switch to the new switch wire by wire and where it's connected might help.
Lastly the brake switch is mounted to a bracket that has a bolt accessible from the passenger side of the steering column. That bolt will allow you to adjust the switches location.
Also you should Google "Chrysler master tech video" and a word like "gauges" or "voltage regulator" the resulting videos are corny but very informative.
I forgot to ask...
Do your e flashers work?
Turn signals?
Tail lights?
