1987 Nissan Maxima/wiring/radio
About
The following is (currently) based on the wiring of my station wagon – after I had done some custom modifications (the notes for which I currently can't find) to retrofit a standard CD/radio into the dashboard, and also after the CD/radio was stolen (ripping out some of the wiring then in place)... so it's not quite standard, but the wiring colors should at least match up where the connectors have been replaced. Please feel free to update or expand this with information taken from other vehicles of this make/year/model. –Woozle
Connectors
There are several parts to the wiring, all of which (I think) normally plug directly into the back of the factory Nissan radio/cassette player.
- nonstandard block connector – #speaker outs
- nonstandard block connector – #power and control 1
- 2 small blue/white connectors on one cable (staggered) – #power and control 2
- 2 half-inch male DIN connectors – these are line-level audio to/from the EQ module
- 2-prong circular #antenna cable (nonstandard)
speaker outs
The Crutchfield adapter brings the connections out with these colors (stripes are black):
| white | left front |
| white + black | |
| grey | left back |
| grey + black | |
| green | right front |
| green + black | |
| cyan | left front |
| cyan + black |
power and control 1
| -1- | -2- | -4- | --- | --- | |
|---|---|---|---|---|---|
| -3- | --- | -5- | --- | --- |
| 1 | pink / red | ACCESSORIES POWER |
| 2 | red / white | HEADLIGHT indicator (dimmer) |
| 3 | black | GROUND |
| 4 | red / green stripe | BATTERY (always on) |
| 5 | green / white stripe / red dots | no idea |
power and control 2
I ended up cutting off one of these connectors and putting quick-disconnects on the wires.
Remaining blue connector (left to right, with latch on top):
- pink / red dots - no idea
- red / white stripe - no idea
Loose wires:
- yellow / red dots - probably antenna half-mast control
- orange / blue stripe / red dots - antenna activation
antenna
Crutchfield's adapter kit for the Nissan includes an adapter for this cable. It's not a perfect solution, however.
EQ connectors
If you're wanting to use the EQ with a 3rd-party player unit, you'll need to find one which has a preamp out/in, which doesn't seem to be widely available (at least not on low-$-end models). The connectors are male 1/2" DIN connectors; you can buy matching sockets from Digi-Key. Note to self: find part numbers.
