MX5 NA - 1994
Decided to upgrade/fix the head unit.
The wiring is interesting…
I assume that the wires closest to the loom are the standard Mazda colours - these seem to have been randomly extended with arbitrary wires, but if this is a known scheme do let me know!
end up in this connector - is this a particular standard?
which then has these two other connectors attached (with different coloured wires again!)
ending in this which attaches to the existing (old, non-original) head unit (a Sony).
Questions - are any of these intermediate stages a recognisable standard? Does anyone have wiring diagrams for any of the intermediate or, ideally, the end connector so I can cut that off and use those wires for appropriate things in my new head unit? I’ll be adding head rest speakers but know about the odd wiring of Mazdas for those - mine is weirder in that an aftermarket hack to add one speaker to each headrest has been done, badly. But that I can solve easily…
