Fw: Radio Install



Luca,

Just went through this.  Erik's guidance for me was very helpful.   (See
below).  Also, Karl has an excellent website showing his install of a Sony
unit.  Don't have the link anymore but perhaps Karl will see this and send
it to you.

Just went through this myself. I will likely be in behind the radio sometime
during the week and planned to map out all the wire colors at that
time...but
for now, if you're chomping at the bit and haven't already begun the
process,
here's how I did the job:

1) Get yourself a multimeter if you don't already have one. I'm not a fan of
digital multimeters for this kind of job...I like the cheap kind with a
swinging needle.
2) The black wire in the car is the ground...find it and attach the black
probe of the multimeter to the ground wire
3) Set the multimeter to DC voltage...whatever will register 12 volts (most
of
them jump from a 10 volt setting to a 50 volt setting...I use the 50).
4) With key off,  poke around with the red probe until you find a wire that
has 12 volts. This is your memory wire.
5) Turn key on. Poke around again with the red probe until you find a hot
wire
other than the one you found in step 4. This is your switched 12 volts for
the main power to the unit. I THINK this wire was light gray, but I'm not
completely sure of that.
6) Turn off the ignition and set the multimeter to 1x Ohms. Start touching
any
2 wires with the two probes until you get one that reads 0 ohms (this means
you've completed a circuit). These are LIKELY to be the positive and
negative
wires for one speaker. I say "likely" because on my car, I found a set of 3
wires that all said they completed a circuit...very strange. I have no idea
what they are...

I was lucky enough to have a jam box handy that had speaker outputs and I
would touch the outputs to the leads I where I found 0 ohms to make the
speaker in question play...and thus I determined which speaker it was that I
had found.

I have yet to find the wire that toggles the power antenna, though.

Subject: 164 LS radio schematic

Trying to install a 91-92 LS radio in a L where the PO had installed an
aftermarket unit which is no longer there.  The unit I have is the
radio/cassette unit and a power amp with a black junction box in between.

Does anyone have a schematic showing the hook up of the LS unit?

Thanks,

Don
