I have a JDM 92' Efini RX-7, just consider it the same as a USDM 1993 R1.

I am trying to put a sony head unit in it and I'm keeping the stock speakers, etc..

I heard there is an adapter that will let me splice the head unit's wires into the adapter and then just plug the adapter into the car's stock harness.

Is this a specific kind of adapter, if so where can I get it. If not, what kind of adapter do I need and what would I ask for at a local audio shop?

To be clear: It never had a bose system in it. It was the non-bose model.

Thanks!

looks like any wire harness from 89 up ford/mazda will work, should be able to get that just about any audio shop

 

metra makes anything you can think of, most car audio places carry it and so do bestbuy and circuit city
