R33 Headunit Wiring Harness Adapter

[Owgasm]

Hi guys.

Finally decides after all these years to change out my tape deck for some better tunes.

I'm just wondering which wiring harness I need to buy. That goes from the standard harness to ISO adaptor/connector.

There are two online I've found but not 100% sure.

PC2-13-4

Or

PC2-76-4

From there it will go iso to headunit(another harness)

I'm aware I could run my own wiring. But I don't want to cut into factory stuff and then when the headunit is outdated. Cut into it again and again.

Thanks in advance for the help.

I should mention, 1995 model

Depends in what unit you are putting in. Go to auto barn or somewhere like that and get the harness for the R33 then also a harness will be needed for the brand of headunit you are buying.
