Headunit Ground

Hey all! I'm going to tackle the install for my Pioneer AVIC-X920bt today and I noticed the ground wire out of the new harness had a ring connector on the end. Where is a bolt at back there that is on metal that I could use? All the ones I saw were on plastic. If there isn't a feasible ground do I just attach this to the stock ground wire (and does anyone know what color wire that is?) also, do I just connect all of my peripherals to this factory ground wire too (like the steering wheel control adapter ground wire)?

Thanks guys!

 

factory ground wire is black as well

 

go with the factory ground.

 

Thanks guys! Guess I'll quick splice into it. Can't wait to get home to do this!

 

Why would you splice back into that ground when your headunit harness already grounds back to that same wire?

I drilled a small hole in the metal bar behind the dashboard/headunit and put a sheet metal screw in it with the ring connector.

 

If you use a harness adaptor that attach to the stock harness then there would be no need to splice into anything. You can get it from walmart auto section.

 

why not? its a factory ground. cant really get much better than that.

its cleaner too if he were to take it out. rather than having a hole drilled in the frame structure of the truck. new owner may not like that.

i say go with the factory ground, ive never had a problem with it

 

yeah wait a sec. what the f?

is it just a ground on the shell of the head unit?

 

Because your harness should already have a ground wire that grounds into the factory wire, by grounding that one you are essentially running two wires back into the same factory ground wire. Take a look at the harness. I have wired many many headunits. The reason they add the extra ground with the ring connector is to ground it to the chassis to get a better ground. Grounds are the Problem and solution to many automotive electrical issues.
