I bought a cheapo CD/MP3-player for the 90 and took the s**te old Sharp cassette player out, as it's been dead for about 10 years now. The player location is in the middle of the "dashboard", unlike a player I saw in a pic, being positioned between the driver and passenger seats. The old set took power through extensions of the cables also powering the cigarette lighter.
I ripped the entire old connector thingy out and was left with the wires (which I didn't label so I'm not 100% sure what's what any more...), which I want to connect to the ISO plugs that came with the new radio. The thing is that the instructions call for several +12v inputs, including one for the radio memory and one that has to be coming from the ignition switch, so that the battery won't get drained when both car and player are off I presume. My question(s): there's a bunch of cables that seem to be lying around; can I just pick a cable measuring 12v and connect it to all the connector ends requiring 12v, excluding the "connect through ignition switch" one, or is there a better way? I expected a three-cable connection (pos, neg, ground), but there seems to be practically only two (never mind the multiple +12 inputs). Any chance I can c*ck it up and have a wrongly grounded radio? I think the old player had a proper ground.
Also, I noticed a diode in one of the connections of the old player, anyone know what it's good for and whether I'll be needing one?
