Reddit reviews 28-pin Head Unit Wiring Harness Adapter Fits Subaru and Toyota

it's complicated, i did it when i first bought my 16'.

and don't let just any audio installer do it, they'll just hack the shit out of the harness.

you need about $200 in parts besides the headunit to do it properly

shit and it looks like the link to the blog on how to do it is gone :(

basically you need:

dash install kit

wire to keep OEM backup camera

30pin adapter you'll cut it in half and use it for hooking all these various things together

Maestro to retain steering wheel control, there's a cheaper version though with less features

adapter to retain USB

adapter for stock antenna

adapter for radio so you don't have to cut anything


and i'm pretty sure i'm forgetting something else.

most of these things all have to be wired into the 30 pin connector, it was much easier to figure it all out on my workbench and solder it properly then install everything, took me about 2 days to do.

no its all basically plug and play. The only thing that you would need to tap wires for would be the stock backup camera. Even then you can just get harness adapters/extensions that can plug in and tap into those....Like this
