No power to radio harness

A few days ago my radio just quit while I was driving. This happened once before right after I installed an after market radio, but it started working again after I pulled and tested the wires on the new harness.

The fuses checked out fine but it looks like I’m not getting any power to the stock harness connections. Any ideas on what it could be? I’m hoping it’s not a frayed or broken wire deep inside the dash.

 

Who wired your head unit harness?

Was it done with purely plug and play adapters?

Was it soldered?

Was it *shudders* hacked up and wire nutted or worse crimp nutted or T-Tapped?

 

I did the wiring myself, but that’s not the issue. I’m not getting any power from the connection where the after market harness plugs in.

No soldering, just heat shrink on the after market harness

 

You cut the harnesses put the bare wires together and heat shrinked them without solder?

 

Here's the diagram, looks like ACC fuse feeds ignition power to the Grey wire and the Radio1 fuse feeds constant power to the Light Blue wire.

 

Do you have any other symptoms such as the dome light not working or power door locks. If so it could be a loose fitting Short Pin in the under the hood fuse panel. NOTE: This is not a fuse even though it looks like one. It is used to disconnect the Stereo, Dome Light and Body ECU during shipment.

Others have also had this issue.

 

It was the head unit, I was probably doing something wrong testing my power the other day but all connections are receiving power now. Radio is still out.

Maybe it just over heated since I left my truck outside all day, guess I wouldn’t recommend a boss head unit if you live in the south. Thanks for the help guys!

 

I see the problem now " Boss Head Unit"...
