With the long portion of the wire through the top of the dash, I started laying the wire on top of everything in the dash. You can tape it down if you’d like. I did to keep it cleaner. I also put the end of the wire right where the defroster vent hole will be.
Take the striped and twisted end of the wire and place it in the antenna plug from the head unit.
I taped the wire in place so it doesn’t fall out later.
Test it out.
I placed the extra wire on top of the head unit
Reinstall the radio and dash.
Here is a picture of the end of the wire in the defroster vent hole.
Done!!
