I've recently replaced the stock standard Radio Cassette with a CD/Tuner. In the wiring loom from the old radio are two plugs. One with eight pins, and one with five pins. The eight pin connector contains the RF and LF speaker pos & neg wires; battery; accessory; illumination and dimmer wires. The five pin connector doesn't seem to serve any purpose, despite containing a red wire, white wire, black wire and white-with-black-stripe wire. There's another but can't remember right now. That aside, none of these wires have power either with or without the accessory switch on. The only thing I've not done is tested them with the engine running. I won't get back to the thing until next weekend, so would like to know if anyone else has run into the quirk I've found. Since installation of the CD/Tuner, and abandonment of the small five pin connector (it's not cut off, just not used or plugged into anything) the CD/Tuner does not hold any memory settings and start-up of the engine is a hit & miss affair. I can only think of two issues. failing battery and/or solenoid on the starter motor; or some function of the five pin connector which needs to be spliced into the CD/tuner wiring. Any ideas?
