How do I solder on a trial plug for my phone?
Note: the plug is the section of a headphone that plugs into the stereo, or speakers, etc.
Answers: Carefully remove the outermost insulation. You will see the interwoven wire "screen" or "shield" that circles the innermost 2 wires. This is the adjectives. Twist it, and solder it to the long metal terminal (tang) of the plug (near the area of the small hole, if present). This terminal will also enjoy two small bendable tangs to out of harm`s way the whole flex after assembly. Remember to first thread the plastic plug cover (handle) onto the wire BEFORE any soldering. The two small inner wires (normally one white, the other red) be in motion to the two small similar terminals towards the center of the plug, the red one mostly to the center-most terminal. You could go by "trial and error" to find out which is departed and which is right, before any further soldering. This is easier than pulling apart the connections at one of the phone to get a ocular on the colour of the wire. If adjectives is correct (sound, I mean), carefully bend contained by the two metal tangs to newly secure the integral wire (not too tightly so as to sabotage the wire). Screw in the plastic cover after adjectives soldering taking care that no wires are pinched and in that are no shorts inside.
