Head Unit Install Question

[TheWastedYears]

There's a braided line w/ a female blade connector that plugs into the stock unit.

What's it for, and what did you guys do w/ it?

Its a ground, just let it hang in there. You dont need it.

let it hang or try to splice it in with the black wire in your new wiring kit

[TheWastedYears]

Is there any added sound benefit to splicing it in? The stock head unit has a lot of alternator whine.

I had an Alpine in my/your RL and just unhooked the wire without any problems. I guess you could splice it into the radio ground but I dont think its necessary.

So I finally realized that RDS vehicles require a special harness... but it still doesn't work.

What am I missing here?
