I have tried to test and change all my fuses changes the multifunction switch and the light controller and nothing changed. The brake lights work just fine when I press the break. The taillights won’t I grabbed a normal wire and connected the +/- ends in a direct connection for the plug that goes into the controller and the lights switch on what could possibly be wrong ? All lights should function properly because it doesn’t hint at a short or anything of that sort, however when the normal wire is connected to the two sides everything functions how its supposed to.

Dash starts and stops a will, headlights don't come on but running lights do. The blue high beam light in dash stays on matter position of dimmer switch. No wont start. Has throttle and injector cordes.
