1989 nissan pick-up, cd player

i tried that no go !here's whats the wires are at the end of the truck .

RED / green strip

large brown wire

GREEN / WHITE strip

3 GREEN/ 1 solid/1 with blk strip/1 with red strip.

3 gray/1 solid/1 with blk strip/1 with red strip .

Here is the correct wiring diagram for your truck, make the proper connections, and you shouldn't have any problems.

Be sure to check your wires with a DMM before making connections. If you still have power failure after that, then check all of your fuses.

      some of the wires in the chart for the 89 nissan don't match mine also maybe it's becuse i have a 4x4 would that make a differance ? also do i have to hook all the speaker wires for it to power up ? thks

All you need to power it up are constant 12v, switched 12v, and ground.

To test to be shure the cd player is working twist the 2 12v wires together on the cd player (red and yellow)  touch them to the positive post on your battery, and the black (ground) wire to the ground post on your battery.

I still say your haveing a ground problem.  How did you test it?  did you just touch the ground wire? or did you actually put on a ring terminal and drill a self tapping screw into the metal frame back there?

              thks alot  97pathy it's working kool  i didn't have the red  hooked up fr the unit to the red fr the truck now that i have the 2 reds and thr yellow hooked up it's working  thks amillion everyone .
