what model is it ? (in old toyota models they used to put abbreviations of connections on the board itself just open and see if that one has it too then we can help ) or else this car seems market specific will be tough to find a factory service manual unless you cough up more info like engine number and model

It’s hit and miss finding pinout diagrams through google. Sometimes you get it, sometimes you don’t. 

Your best bet is to make friends with  someone who works in Nissan or a mechanic who has Alldata software.

Or, there are plenty of tool shops in Sharjah who will sell you a laptop with a cracked copy of Alldata and loads of other software for 500 dhs. Worthwhile investment, will pay for itself in one job. You can even download cracked software but it will only have information for older cars, which isn’t an issue as you’re working on an old sunny. 

The easy option is to take the cover off the plug and see where the wires go.
