'83 corolla wiring?
Hi all,
I'm trying to install a pioneer tape deck/tuner into my 83 corolla wagon. I've installed car stereos before but never into a car this old or complicated. It currently has a factory AM tuner in the top of the dash and a separate cassette player (without a radio) at the bottom of the dash. I'm going to leave the AM tuner there and take out the old cassette deck. Has anyone replaced a setup like this before? I'm having a few problems and all the wires are either blue, blue and white or blue and red so it's hard to tell what they all do. The two units appear to be in series rather than parallel (ie. the AM tuner is wired directly to the car and then tape deck is wired from the tuner) and this complicates things. A couple of specific questions: 1. The car appears to have common ground speaker wiring, does that sound normal for a car of this age/type? 2. Being an old car it doesn't have a constant power wire, what's the best way to get constant power? Run a wire directly from the battery or hook up to something with constant power like the clock? 3. I'll probably totally rewire the speakers to avoid the common grounding issue there, but is there a way to identify the main grounding wire for the power supply? Thanks a lot for any info. I've looked through a lot of sites but none are particularly helpful apart from the basic stuff. If anyone can recommend any sites or forums that would be great too. thanks heaps matt Some supplementary info if it helps: It's a 1983 KE70 Corolla wagon, 2 speakers. The replacement head unit is a Pioneer KEH-1060. The two existing units appear to be factory units (they are both branded 'toyota by philips'). As I said, they appear to be wired in series. If I take out the AM tuner, the tape deck doesn't work. All the blue wires seem funny to me, I'm wondering if it's been rewired at some stage for some reason. I've identified the ACC power wire and the left and right positive speaker wires but that's about it. The speakers aren't really an issue, I can rewire those. The main problems I have are getting constant power and finding the ground wire for the power supply. --- Outgoing mail is certified Virus Free.

'83 corolla wiring?
OK, I found a site that answered one of my questions. I can just make my own
grounding wire and screw it to the chassis. So assuming I rewire the speakers I just need a constant power wire. So am I better off running a wire directly from the battery or running a wire from the clock or internal light? Or does it not make a difference? I'd still like to hear from anyone who has had experience with 2 units in series. thanks matt "Matt Lobegeiger" wrote in message ...
