I installed this in-dash 6 CD changer which I got off of ebay into my '93. The changer is meant for newer Nissans and subsequently uses the newer style radio harness from model year '95 on up. In order to retrofit this into my 93 I bought 2 coversion harnesses from Nissan. They are parts numbers 24028-3B300 and 24028-0J300. They convert from old to new and from new to old. You will need both for this CD changer, but only one for installing a 95+ radio. Sorry, I don't know which one is which (they weren't individually labelled)
