Wiring for audio jack on a belkin fm transmitter model f8z439 the wires are purple yellow and green insulated with a bare copper strand surrounding the

The core conductor of a coaxial cable, which is often a solid copper, stranded copper, or copper-plated steel wire, is surrounded by an insulating layer and is completely encased in a shield, which is normally made up of one to four layers of woven metallic tape and braid.

Sorry that diagram is not available here.

White wire with bare copper wire around it is for video. Center wire is positive, copper bare wire is ground. Red is +12v dc, Black is -12v dc, Green is audio +, while yellow is audio -.

Blue goes to A, Purple goes to G and Green goes to V! I need to know what the pinout is for the headphone jack side

Find the Hot wire:
Your switch has 2 wires. One of these wires is Hot, and one goes to load. Disconnect wires from switch. Turn on power. Do not stand on wet surface. Test each wire to bare copper wire. When tester lights up, that is Hot wire. The other wire goes to load.

Connect wires:
Hot wire goes to Black timer wire
Wire to load goes to Red timer wire
White wire connects to white wires that are twisted together
Bare copper wire connects to Green wire from timer

How to connect white wire to white wires that are twisted together.
a) Strip white timer wire so you have 1-1/2 " of bare wire. Stranded wire will wrap around other wires easily.
b) Remove wire nut. DO NOT UNTWIST wires.
c) Hold all whites together so bare copper lines up. Wrap stranded copper around the twisted wire.
d) Replace wire nut, or use larger wire nut. Twist real tight. Do not use tape. You can solder the connection.
e) When done, pull on white time wire to make sure it is held tight. Push whites back into box.

Rotate the iTrip AutoPilot FM Transmitter controller so that its buttons are facing up and its data cable is on the left side. The data cable wires attach to a row of contact points along the left side of the circuit board as follows (from top to bottom):

1 = Purple
2 = White
3 = Blue
4 = Red
5 = Black
6 = Brown
7 = Green
8 = Yellow
9 = <unused>

What you have is a stereo plug.
You would twist the outer strand together and solder those as shown in some of these pictures

Some of the pictures will take you to sites that actually show you how to do it

Each of the rubber covered cords running to each ear piece has two fine strand wire bundles inside. The right ear piece has a red colored strand and a copper colored strand. The left ear piece has a green colored strand and a copper colored strand. The wires are coated with an insulation lacquer. The lacquer burns off when you heat the wire for soldering.

Repair item: 3.5 mm stereo headphone jack, shrink tubing

Plan for strain relief:. These headphone wires can't take any tension at all. You need to crimp the black cords to the headphone jack somehow.

Slide strain relief and headphone jack housing over the over the rubber covered headphone cord.

• You need to plan a way to relieve the pulling stress on the solder joints where the two headphone cords enter your replacement headphone jack.
• Try shrink tubing if you have it.
• If you have some thermal shrink tubing, slide a piece over the headphone cord end before stripping the wires.
• Slide the headphone jack casing over the headphone cord also.

Strip each headphone cord 5/8" using the 18 gage setting of your wire stripper..

Hold each headphone cord in a "third hand" soldering assist tool and tease the green, red and copper bundles apart..I wore a 10x Magnavisor and I used a sewing needle and a bright light.

Twist the copper colored strands from both headphone cords together. They are the common ground wires. The copper colored bundle will attach to the headphone jack ground.

Apply a dab of solder to the end of each of the three bundles of wire. You will see and smell the insulating lacquer as it burns off. Keep most of the wire bundle cool.

Position the two strand headphone cord and the 3.5 mm headphone jack in the third hand soldering stand.

• Plan where you can crimp the headphone cord. Crimp it when ready.
• The green == left channel wire goes to the tip of the 3.5mm jack.
• The red==right channel wire goes to the middle of the 3.5 mm jack
• The copper colored wires go to the ground of the jack..
• Measure resistance, 31 ohms per earpiece.
• Screw the jack cover on and finish the strain relief craftsmanship.
  

There was a black wire included (with a metal "cap" to insert in the FM center connector) that served as the FM antenna, but in a pinch any wire can do, preferably about 33" long and with the insulation stripped from the last inch or so (or get creative and sand the last inch of varnish off a properly sized untwisted clothes hanger and gently bend to suit). Bare stranded wire should be twisted or folded until it's thick enough to firmly fit the middle "hole" of the FM antenna connector. Be careful that no strands of wire short to the metal ground "ring" surrounding the hole or the antenna won't work (although it won't burn out your amp like shorting the speaker wires would, it just won't work). Orient the wire horizontally or vertically for best reception. This unit also doesn't pick up FM very well if you're in a steel-framed building or away from windows in the general direction of the local transmitters, so moving the unit closer to a window may help dramatically. In bad reception areas you can get an external FM "rabbit ears" type antenna but you'll need the "European" style of 300 ohm to 75 ohm transformer to plug it into the unit's FM connector (one that has a bigger central connector "plug" than the usual US units). Some cable systems also still support FM, if yours does, a VHF/UHF/FM signal splitter and either the above mentioned transformer attached to flat 300 ohm cable or a plain  "European" style connector attached to the end of the 75 ohm round black cable will do the trick. Some Radio Shacks have them. Good luck!

I opened up one of my Cobra HighGear mics and here is how it is wired:

1. shield (Bare copper wires) --- twist them good and tin with a little solder

2. audio (White)

3. transmit (tx) (Red)

4. receive (rx) (Black)

Blue and Yellow are unused.
