No stereo earth??

Hi there, great info in here. In my 89 VN i have 11 wires at the stereo connector and none of them seem to be a ground. Could the original stereo have used the case and mounting screws as the ground when screwed in ??
There is no black wire in the loom and the car does have an electrical aerial.
These are the colour wires i have and from this site i think these are what each colour wire is for.

Orange/white stripe = constant 12V
yellow = accesories
yellow/red stripe= elec aerial
Speakers-
light green(+) & dark green(-) = front right
tan(+) & grey(-) = front left
blue/brown stripe(+) & blue/black stripe(-) = rear right
brown/black stripe(+) & yellow/bluestripe (-) = rear left

Any suggestions
Cheers

Yep your right there about the wiring colours. I think the earth should be in the centre of the stock plug??

Anyway generally i dont use the factory earth wire, i either make my own by routing a wire to a solid metal section, but with the VN-VS commodores i dont connect an earth wire, the unit earths through its chassis and the stereo screws to the metal frame so thats as good an earth as your going to get bar running a 12awg wire straight to your battery

So yep, basically just connect all the other wires and make sure not to turn the head-unit on without mounting it first, otherwise it will try and earth through the antenna cable (not good).

Thanks mate,
I partly pulled apart a mates stereo at work during lunch today and it was different again.
It had no black at all but there was a white one in there, same year as mine.
maybe only early models used the case as earth.

Should be able to get to it tomorrow and get some tunes going again

Cheers

Hey Atriedae, thanks for the thread.

Followed your instructions to a T today to replace my dying head unit and didn't have one problem at all. Was reluctant to use too much force initially but I picked up the meaning of persuasion pretty quickly.

The last time I did an install was in my LX Torana in the late 80's which was just a little bit different !

This thread is a godsend.
