Hello all.
I just bought an 02 protege5 and the more i look at it, the more i find has been done to it. For example, one of the previous owners installed a siren in the grille, the wiring to which no longer functions, but nonetheless is there. The same guy, i assume, put in an aftermarket receiver and kinda completely botched the wiring. The receiver resets to factory and goes through demo mode every time the car is turned on. It's fricken annoying. I've been trying to narrow down possibilities by going through the wires myself. Here's what i've discovered.
The ground cable is completely useless. It does not have any voltage ever.
The stereo only turns on when both constant voltage power wires (from the car and from the deck) are in contact with both ignition power wires.
When the ignition power wire from the car is in contact with the constant power wire from the deck, the stereo does not turn on, however, the dome light works and the beeping to tell you the door is open also works.
When the wires are done properly, (constant to constant, ignition to ignition, ground to ground) the stereo has no power and the dome lights and door alert do not function.
It's kinda looking to me like this guy messed up the wiring elsewhere in order to, idk, put in a siren or some other essential like that paramount to having a working stereo. I hope that's not the case because if it was, there are a million different places he could have frigged it up and it could take me as many years to find it. I'm posting in hope that someone else sees something i don't and can point me in the right direction to having my stereo work!
Thanks in advance
