I just picked up a used avic-d3 but the RCA harness is missing the rear and sub outs. It seems like a lot of avic gear uses the same connector jacks on the head unit for the RCA breakout or the power harnesses. However, it seems Pioneer has unique part numbers for the D3 vs previous units. The question I have is are any other harnesses compatible with the D3? I'm good at repair work so I have no problem building the correct harness if need be, I would just need the pinouts.
The D3 cables are around $50 each, and while that may be cheap when compared to the MSRP of the head unit, that is almost a third the cost of a used unit. I see z series cables much cheaper on eBay.
