I know this is probably a rediculously simple question for you guys but
I am your typical back yard mechanic who only just graduated from the
days of
8 tracks, cassettes and speakers lying all over the party wagon.

I've just installed a new cd player, amp & speakers in my 99 wrangler...

no problems, just plug in with install kit.

My problem is my daughters' 94 Olds Eighty Eight.
I bought her a Pioneer cd player for Christmas and now
must install it using factory speakers.The harness to OEM stereo has
wireing to engine control system, heater controls,
diagnostics etc.
What do I do with these?

Do I have to leave the OEM radio in and splice into it?
how does that work????

Any help would be appreciated.
Thanks
Doug

The radio harness in a '94 Olds shouldn't have anything to do with engine
controls, heater, etc. They might lead into the same bundle, but the radio
harness is separate from the other connections. The only extra thing I can
think of that might be attached to the radio is steering wheel controls,
which won't work directly with your Pioneer anyway.

The easiest way to do the installation is to purchase a wire harness made
for that vehicle. It's a different harness than most other GM vehicles of
that year, but as long as you get the right one, replacing the radio should
be simple. There's definitely no need to keep the stock radio in the car.

Thanks for your response,

I don't know har far you are willing to go to help with this,
so I'll just give you this info and cross my fingers.

I mispoke a bit by not be very clear. The actual plug from the harness to the
exist. stereo has about 16 wires that go into the radio from it.
The "typical radio circuit Pontiac/ Olds" wireing diagram I have (Haynes
manual)
shows some of these wires coming from the radio as follows...

"Data line" out to "heater & A/C control assembly"
"Dim signal out w/ electronic A/C only" out to heater & A/C control assembly
"Data line" out to "Asembly line diagnostic"
"Speed input" out to "engine controls system"
"Dim signal input" out to "interior lights system"
"Panel light " out to "interior lights system"
(all quotes are mine)

I have already picked up a plug that is supposedly for this car (metra 80-2001
smart cable)
It has the standard stereo connections coming from it (14) to wire to new
stereo plug.
There are no provisions for the wires listed above. These wires would dead-end

@ the new plug as they come from the car harness.

Additionaly, the wireing from the new pioneer does not have the typical blue
wire
for power antenna. What do I do here?

Thanks again for your response,
If you could help me out any more I'd be grateful.

Thanks,
Doug Anderson

I wouldn't worry about the extra wires. I don't know exactly their purpose
is, but I have never seen or heard of any problems arising from replacing
the radio in these cars. "Speed input" was used in some GMs to create a
speed-sensitive volume control (radio gets louder as the vehicle goes
faster). Your Pioneer doesn't use this feature, so no need for the wire.
Other wires connected to the panel lighting make the radio illumination
lights dim with the other dash lighting when your lights turn on. 14 wires
are just the same radio connections you'll find in any car: 8 speaker wires,
constant power, accessory power, chassis ground, two illumination wires,
power antenna. Just connect the ones that correspond to the wires on your
Pioneer harness, and make sure the others can't short out on anything, and
you'll be fine.

The Pioneer harness doesn't include a blue antenna wire, but the blue/white
remote turn-on wire can handle this function (if the vehicle is equipped
with power antenna).

KaeZoo...
