Looks like something that has come from Korea not an Alpine unit?
Likely tbh, just a lookalike - in that case, chances of finding the connector to it are slim to none I'd imagine!
If there's a manual stating what connections are what on the back you can get a blank ISO and chop it to it quite easily with connectors and a crimper. As everyone else has said it's the same layout and colour scheme as Alpines (same as the one my mate's got anyway) but it doesn't say Alpine on it, so it's presumably a chinese/korean cheapy type.
all an ISO connector does is match up the wires coming out of your HU to the ones coming out of your car, with a blank ISO lead you can just match them up yourself if you can find the wiring diagram for your car's connector. Wouldn't take long![]()
