R34 GTT Stereo flashing on and off

[tsyk3s]

Good Evening all,

I recently tried to hook up an aftermarket stereo to my Skyline, but after hooking it up it had no power. So I hooked the old one back up and now it’s doing this.

Does anyone know what the cause could be? I have checked the fuses and they all seem to be fine, so I’m stumped.

It is not getting enough power, probably through an Accessories 12v circuit. 

When you installed the new head unit, what did you do? Was it direct fit or did you need to do some wiring?

Thanks for the response. 
It was an AeroPro harness. Plugged it in, didn’t work with new stereo, unplugged harness, plugged in old stereo and it was like that. 
 

All other interior electronics are working fine.

I had to buy a harness that sits between the OEM harness and the aftermarket stereo. The adaptor harness had its own earth, perhaps its that. It should be a pretty simple thing to install.

Check the loom connection thoroughly, wiggle the wires while it's plugged in. I have a feeling 12v has a bad connection it's not getting enough power the way that screen is flashing.
