Car Stereo Harness?

[MoelyCrio]

OK, my new MX5 needs a new stereo, so I’ve got a used one from eBay whilst I consider my options.

In the car was an Alpine unit with 16 pins (bottom). The new unit is a Aldi Tevion unit with ISO connectors (top).

I think I need a male Alpine 16 pin > ISO adapter, but I can only find something like

Which will fit the old unit, but not the bit attached to the car. Do I need to get some custom made harness?

Ask at your local Halfords. I know people ridicule Halfords but their installation technicians have served me well in the past.

Normally Alpine headunits come with an ISO to Alpine adaptor, so you would just remove that and use the Mazda to ISO adaptor that was there before - unless it was bodged in before.

If you haven't got a Mazda to ISO connector they're about £10 on eBay, but you should be able to pick one up from Halfords too.
