i have a factory cb, and i will instal it in the pickup.['78 supercab]
i don't know what the exact location is.
i don't know where i can conect it, i can't find a conector that fits on these.
it's a 4 point conector with a yellow/black ,lightblue/brown wire end two thin wires lightblue/red and darkblue/red.
did anyone know what is the +/- and witch are for the speaker?
sorry for my english, i com from the netherlands.
the early 80's ones were located under the driver's seat. Just about directly under the driver. (Bench Seat)
The Cb was located on, or in the center console for Buckets.
On the 1979 ford wiring diagram,
I'll provide the connector #s for reference if you have a Ford wiring diagram handy. the numbers will not be located on the truck itself.
The Yellow/Black wire that hooks power to the factory Radio, is where the power to the CB comes from.
On trucks without the CB option, the radio plugs into the main harness radio connector. (Connector-506 or 506A)
On trucks with the CB Option, but without the stereo radio...
#1: A harness extention hooks to the main harness radio connection (C-506-A). From there it goes to the radio connector (C-506) where another yellow/black wire splits off from that connector.
#2: Follow that yellow/black wire and you will come to another connector (C-530) where another harness extention plugs in. From Connector (C-530) one wire goes to the CB Reciever/Transmitter Radio. at connection #(C-532). The other wire goes to the CB Radio microphone.
The speaker is connected into the radio speaker harness that goes to the dash.
On trucks with the AM-FM stereo, and CB.
#1: A harness extention hooks to the main harness radio connection (C-506-A). From there it goes to the radio connector (C-530) where another yellow/black wire splits off from that connector.
#2 The Radio connects to this Connector (C-530) while the other goes to a C/B radio suppression choke, that's spliced in (Splice #503 (S-503) ) After the splice (S-503), the wire changes color to black goes through the choke, and hooks to another harness extention at connector (C-530).
#3: From Connector (C-530) the wire changes back to yellow/black and splits off. One wire goes to the CB Reciever/Transmitter Radio. at connection #(C-532). The other wire goes to the CB Radio microphone.
The Cb Radio is hooked to the Center speaker located inside the dash. and is seperate and not hooked into the door speakers.
thats the metal box and the am/fm radio is the same as on the pic you shown in your first reply.
if y remove the 4point connector, can i put the yellow cable's to the + and the blue at the -?.
the thin wire's are for the speaker?.
in your third reply they said the cb is under the driversseat. mounted on the floor?
and the wire? onder the carpet?
on top of the box D.O.C type approval
D.O.C type C5FD8800 series
on the side with the connector under the fuse 9071
under the antennaconnector 198002
on the underside moterola inc
fcc transceiver data cb 1134
type accepted for part 95(d)
certivied per part 15c
thats all that i can find on the cb.
is it not possible to instal the cb without the radio?
do you need a special radio for a cb?
the radio in my truck is orginal and i have the cb from ebay.
my truck didn't came with a cb.
It looks like with the info given here, that he may not have the wiring harness extention that goes from the main harness radio power connector, where it splits off, one goes to the cb, and one goes to the music radio.
According to the late 70's wiring diagram, (Mil1ion posted it for me earlier up the thread) for the CB, on a truck with a stereo radio, the CB has an isolated center speaker, that is not hooked into and is isolated from the stereo.
On trucks with mono, AM or AM/Fm, there is an interupter placed in the speaker wires from the mono Radio, and the CB and Mono radio share the center speaker.
