QuestionWell i have a 1979 280ZX and i want to put a Jensen Tape deck into it. In the 280zx the audio system has a connection (female). The Jensen tape deck does not. i tried to splice the wires but it did not receive power. and I've tried looking everywhere for a wiring diagram but i have not found one this might be a simple wiring problem but my field is not of wiring. could you help me?
AnswerHi William,
Well, what you should have done is bought a Nissan to DIN adaptor harness from www.autotoys.com , not cut the wires as all decent modern radios are now ISO DIN plugged.
But having done that...
I assume that as you bought the radio it came with wiring instructions so it is the car that is the mystery, so I attach my instant experts fact sheet which so far has had a 100% success rate and with the Nissan pin out and std colours also from autotoys tech section.
Armed with this lot and a basic knowledge of electronics you will be able to sort it out.

Not all sections may be relevant, use what you need.
Check out the car is NOT the problem first though, had many a customer change the radio to no avail when it was a simple fault on the car.
You will need a test meter set to 20vdc or a 12v lamp or test probe.
I run this test when working on a car where a previous owner has ripped the connectors out of a used car and the new owner is in the same boat as you so it cover all the basics and should sort you out. So armed with your 12v probe or test meter, some paper, masking tape and a felt tip pen, here ya go!
Speaker wires. (non-amplified) these are tested with a AA battery across a pair of wires and you will here a 'pop' from the speaker,
These are normally twisted together in pairs (if you are lucky) and usually in a loom of their own before going of to the four corners of the car and are the same colour for each pair but one with a colour trace on, i.e. blue and blue/white, green and green/white.
Label it (e.g. left rear), continue until all four pairs are identified and labelled.
Earth one side of your meter or tester to a metal part of the car, probe each wire until you have a wire that is live all the time with the ignition OFF, label this ‘+30’.
Switch on ignition and redo test until you find another previously dead wire now live, this is ‘+15’.
Switch off ignition and switch on the side / park lights, repeat test until you find a third live, label this ‘lights’. Switch off the lights
You should now have two or three left. One will be earth, (usually black or brown); one could be to an amp and or electric ariel (usually blue or blue white) and one for phone mute if fitted. Clip tester to +30 and probe one of the remaining wires, if you have an electric ariel it will go up. Connect your DIN plug to the correct wires and jobs a good un’.
DIN connections are.
