Purchased while replacing head unit for a 96 Maxima (with factory Bose system). In the end it worked great, but the instructions leaved some to be desired. See Cons for list of wire color discrepancies.
In my setup I wired up the 8 wires for the channels, plus Red, Yellow, and Black as directed. The Blue (Power Antenna/Remote Amp Turn-On), labeled as Blue/Blue White in the wiring diagram, was not used since I am also replacing the power antenna. At this point I had power (lights) but no audio, and Orange, Black/White and Blue/White unused (along with straight Blue listed above).
The Blue/White wire had a flag hanging off it labeled system remote control, which I thought indicated it was an "antenna" receiver for remote controls that some head units have. This wire was the key - it needs to be stripped and connected the corresponding Blue/White wire from the head unit. After this I got sound.
My Maxima is also bizarre in that the unit will not power on (no lights or sound) unless the antenna is fully connected. I believe it grounds through the antenna (even if replacing the head unit and power antenna). I tried connecting the extra Black/White wire to the Black (Ground) pair, hoping this would bypass the need for the antenna to be connected before the unit would even power up, but this did not affect it. I left it connected anyway. In the end I had an unused Orange wire, blue wire (since I'm replacing the antenna), and should have had an extra Black/White.
Pros: Works as advertised, required for 96 Nissan Maxima Head Unit replacement.
Cons: The following are issues between the Wire Color Code Chart (WCCC), Wiring Diagram (WD) and reality
LF +/-, RF +/-, LR +/-, RR +/- , Red, Yellow, Black all exist as listed in WCCC and WD correctly.
Orange exists, listed in WCCC, not listed in WD
Pink doesn't exist, is listed on WCCC, not in WD
Black/White exists, not listed in WCCC, not in WD
Blue* does exist, and is regular Blue. Listed in WCCC, labeled as "Blue/Blue White" in WD
Blue/White exists, not shown in WCCC or WD, note is not reg
