I found another diagram under "Antenna". This should help clear things up.2w - two white - 12v out, go to the antenna amplifiers
1br - one brown
= A solid brown is the chassis ground. It used to just clip to the old radio on it's own tab on the back of the case. It is a ground1bl-w - one Black/White, thin front speaker positive?
1bl-g - one Black/green, thin front speaker negative?
1r-br - one Red/Brown -
1br-g- one brown/gray
- Alarm? I do not think it is used in the US
This is the best I can come up with without further feedback from you.
Do you have power and ground wires figured out, and does the radio power up? Do any speakers work, if so which ones? This is where you need to start if you have not yet done so. The by process of illimination you can figure out the rest. Also for the speakers a dry cell battery (C cell or D cell) works great.
Other possibilities to explore;
It Has the Black/White (+ L/F), and Black/Green (- L/F)
wire going to the left front speaker. If you hook a D or C cell battery to the two wires, the speaker will "pop". If you hook the + wire to the + on the battery, and - to negative, the speaker will "pop" once outward if you can see the cone. If you hook up the wires out of phase it will "pop" inward.
The schematic shows the same color wires for the R/F speaker and is likely a typo error. You will notice however that these are the same size wires as the L/F wires which are smaller than the other wires in the harness. So the other two smaller gauge wires should go to the R/F speaker. You can test for "phase" with the battery as above"
Let's start with that hook it all up and let me know what does and does not work. Check your wiring colors carefully (use a magnifine glass if necessary) and tell me the colors, and size (thin/medium/thick). Please write it out so there is no mistake with your abreviations
