Audio Systems: pioneer headunit, rx7 series 1, pioneer headunit

Question
Kelly, i have just bought my second RX7(series 3) which has a pioneer(DEH-523) and want to swap with the headunit out of my other RX7(series 1)(JVC[KD-SX985]). Just wondering if you know what colour is what on the pioneer loom as i know which is which on the JVC deck. Maybve a site with a wiring loom diagram for the pioneer headunit.

Thank you

Answer
Both brands use EIA standard colors, other than the Pioneer may have a different color memory power wire. They used to be orange, rather than the standard yellow. Use a test light to confirm power wire function on both cars before swapping.
Otherwise, the colors should be identical.
