Help Soldering 3.5mm Stereo Jack

[DanMcQ]

Hello,

Pardon my ignorance and possible misuse of nomenclature, as this is one of my first attempts at a DIY stereo project. I am attempting to add an auxiliary jack to my car. I have been using a Monster Cable that plugs into the stereo with 2 male RCA connectors, and at the end there is a 3.5mm male stereo plug. I've cut off the male stereo end, and inside the monster cable I was a bit confused - there are three different sets of wiring. There is an outer silver wiring (which I assume may be shielding), and then there are two sets of two wires. One set is a blue and a green, the other set a black and a red. Basically I am quite confused as to which cables are going to be soldered to which terminal on the stereo jack. Here is a picture of what I'm dealing with:

Was having trouble posting the image above, but I figured it out.

Do you have a meter that you can do a continuity test?

I don't, but I managed to figure it out through trial and error. Turns out the Red is the right channel, the Blue is the left, and the Green/Black are the ground.
