The guide that should never have been written

You should never need this guide because these are the speaker wire pairs with two pairs for the front and two for the rear speakers. They are standardized ISO wires that should be fitted correctly and neatly into the standard ISO connector plugs that every universal Android headunit should have.

It is never worth cutting the corner and getting yourself a universal Android headunit that doesn’t include ISO connectors, but if you have one, this guide is for you.

(we feel your pain of time wasted that would have been better spent enjoying your new toy).

A custom-fit Android headunit will never need this guide. The custom-fit androids are a perfect fit, complete with factory-style plugs. These factory-style plugs are not universal but tailored to fit the vehicle without any adaptation.
