Hello Everyone, I recently got a D3 and the previous owner did not haev the RCA harness for it. I have looked at pioneer replacements and ebay, but it seems expensive. Anyone on here have an extra to sell or know of a cheap place to buy one? Thanks for your help!

I do, make me an offer and we will begin negotiating. Send offers to me via PM.

Pioneer is the only manufacturer of those harnesses. You're not going to find an aftermarket D3 harness. Either get one from Pioneer, get one from Ebay, or maybe somebody here will sell you one. Those are pretty much your only 3 options.

There are a few on eBay, I'm looking around for the harnesses as well.
