yeah,there's no ground wire in the harness. If I remember correctly,there is a 10mm bolt on a bracket behind the radio,and I used that as my ground.
My Rodeo has stupid wiring. I got the adaptor harness for it,but it had no ground wire. It had the red and yellow power wires,but when I hooked up the yellow wire,the deck wouldn't work,but it would turn on my parking lights. I ended up having to use the red wire as my power wire and ground the deck right to the battery. So now,whenever I turn off the truck,the radio stays on,so I have to remember to manually shut it off every time. That's the only way we could get it to work.
