Harness for replacement head unit

I have an X-reg Micra. It's an automatic 1.4, four door with two speakers but wiring for four, I believe. I've been trying to fit a new headunit (Kenwood) but the harness adaptor I was advised to buy is the wrong one. I've taken some photos of the connectors for the existing stock cassette player. Can anyone please tell me what harness I need as I'm a bit confused. It certainly isn't the PC2-77-4 that I thought I should have. You can see photos of the unit here:

Thanks very much
