Short Backstory: allowed my brother to install a sub system. He jacked up the wiring believe he split into the wrong remote wire behind the stereo. so you had to disconnect the subs at the amp or theyd kill the battery.
The wife decided to have another guy "fix" it. Ended up with a three wires under the driver seat that had to be twisted together If you wanted the tail lights (plus some other cabin lights like the door handels ect) and subs to be powered and work.
I have tried cutting the blue radio wire behind the stereo and the spliced wire behind the rear stereo console. Nothing is working and Im getting sick of having to flick a "gheto rigged" switch to turn on tail lights.
Im positive if I were able to revert the wiring to factory Id be able to do the install my self. so just any help is much appreciated
