Hi ...
I’m new to car audio systems and this is my first time installing a stereo. So, please bear with me if I give too much or too little info. If you ask, I shall answer, but I have a feeling there's more than you need here.
I am going to replace the stereo, speakers, and speaker wire in my ’93 Lumina. During my planning I encountered two extra unidentified wires in my dash. I have identified the wires for the speakers, the ground, constant power, switched power, dimmer, illumination, and power antenna. In short, I'd like some help with what these 'extra' unidentified wires are for and what I should do with them.
The factory stereo was recently replaced with a unit that had been sitting in my garage for many years and no longer works. This unit was installed without a harness. (I now have the appropriate wire harness/adapter. However, I have decided not to use it because I would rather not reconnect all the factory wiring, I am replacing the speaker wire anyways, and with the harness there would be an
overabundance of wire length in the dash.) When the first upgrade was installed, the two 'extra' wires were not cut and are still attached to the same factory connector. They are the only wires on this connector. The spot for it in the wire harness/adapter has no wires extending from the opposite side to connect to the stereo harness and the manual that came with the harness and mount does not address this connector's wires at all like it identifies the other three. It appears that it may be useless, but I’m not certain of it. I simply can't think of anything that would be useful to a factory stereo and not an
after market one. But, I admittedly know very little on this subject.
Any guesses as to the purpose of the two extra wires? Or are they useless?
Should I simply leave it as is in the factory connector? Or cut them and close them with a connector or something? If so, I plan to use one butt splice for each wire and crimp both ends to seal it off – will that work?
Any help figuring this out will be much appreciated. I just want my first install to go smoothly and not create more problems than my current problem – no music!
Thanks for reading and I hope I didn’t give you too much unnecessary info.
