electrical madness

Trying to figure out wiring for radio. This area a mess from previous owner. No equalizer or retractable antenna.
q1) with the antenna there is a wire. Where does it go. Can not make heads or tails on wiring diagram. Do not have electric ant. In window.Called the plug for the antenna amplifier - can not reach the amplifier.
q2) where can I find the heads that attach to the ends of the wires that go into the back of the radio ( 4 ). 2 have been cut off.
4) I figured out the hot wire ( constant)
q5) Have multiple sets of wires coming from the trunk line with the main set of wires to the radio. Have no idea where they go.
I have ( I believe ) accounted for all switches but still investigating.


Might anybody have an idea or better yet a pic of the area. I have manuals out the yin yang ( factory, haynes ) but no luck.
Any suggestions

thanks

I recently had all that figured out but since I closed that area up I haven't given it much thought.

There was a thin (18 gauge) wire that was with the antenna wire, yes the amplifer wire, I assesed from the existing connectors and a scematic that I had that it gets hooked to power (switched from the radio) Power on, when radio on.

Atop my factory Blaupunkt were four colored dots on a sticker. That was the key to the speaker wires. somehow I was able to ascertain that the colored dot refered to the colored wire pair for each channel of the chassis speaker wires.

Standby one......... I'll go see if I can find my tech data.

OK, I'm back.

Speaker codes as follows:
White, Yellow, Black and Red.......

White- front left (drivers)
Yellow- rear left
Black- Front right (passenger)
Red - rear right

*Brown tracer is the negative (-) of each pair.
I.E. white/brown is the (-) for the front left speaker.
white is the (+) for the front left speaker.

CONNECTIONS at back of radio.

1- ground connection, plug
2- ignition lock term.R, plug
3- lights
4- antenna amplifier (autom. ant.)
5- permanent positive term.30, plug
6- (was not specified)

Disclaimer..........This information given with my best intentention from my interpatation of the "Wiring Diagram Type 944, 944 turbo, 944 S Model 88 page 13. Radio Coodinates 81-90"
I used this info to connect my 1987 and it seemed to work just fine although I beleive this to be the schematic for a 1988 In other words use this information at your own risk.

Best wishes and let us know how it worked!

Thanks for te info. I'm about to do an install and was just planning on testing it with the fader and balance. This will be very useful!

Lemme know if ya need more info , I didnt have a fader installed in my 87 so I didnt include wires info for that.

I did learn about.... that, I think I can find a dimmer wire to connect the radio lights to. It is so bright on full all the time that I cant see my dim VDO Gauges....hehe

Sometimes the best way to know a subject is to teach it............. Or is that those that cant do, teach...........

Bon Chance!
