Trying to install new sony xav-ax3000 in a 1990 subaru legacy; doesn't turn on.

Hi.
So, I connected the wiring using butt splices by referencing these two things:

subaru - https://www.surrealmirage.com/vrg3/bcstereo/
sony - https://cimg9.ibsrv.net/gimg/rennli..._118d1aaf63cda9e3b3c45406d48216d33e8d27ff.png

Left disconnected are the parking brake, reverse, and REM on the sony side and the subaru side, one Accessory +12v, Illumination (-), and Power antenna control are unused.

I connected the ground, then the power (accessory 12 and battery 12) then all the speakers to the sony harness and then plugged it into the device and turned on my cars power.

Nothing happens.

Assuming the head unit is fine (it's brand new), any idea what's going on?

Have you confirmed that all the wires coming out of the dash are what you think they are? Check your radio fuse in factory fuse box.
Also you can connect that parking break wire to ground.

I see you have 2 yellow/red (+), confirm the one connected has constant power.

Did you disconnect the battery before you tried to re connect the HU
If not like hispls said you probably blew the fuse

Does anyone know how to find out what model these sony headset are through its settings?
