    It was probably overkill where I ran the ground to but I ran it down to the center console by the shifter and placed it under a bolt there. I couldn't find a good place up by the head unit and didn't feel like drilling into that frame bar in the back. Someone else may have found a more convenient spot.

    Unless you are running new power wires (something else needing power - radar detector, new 12v outlet, etc) then the factory ground is a good spot. If you can trace it back to its grounding point that is the best bet (not feasible in some vehicles), but you should have no issues using the harness ground for something like this.

    I think the harness ground wire may be inadequate... I am getting some feedback and I think it may be that little ground wire. At some point I will figure it out.

    I did this bypass in an F150 about a year ago, not this truck, but I believe (though I dont know for sure) the parking brake sensor is on a different circuit than the chassis ground for the head unit, and would be surprised if it is intorducing noise, but I would consider a small drill bit, then a self-tapping screw into the brace behind the dash as a grounding point to test it. Double check, but that *Should* be about as good as it gets.

    Use the ground in the wiring harness. installed my new alpine HU a couple of weeks ago, with new amps and subs, and no feedback or anyproblems. I have a 09 as well OP.

    Do I used the power antenna wire on the ta02b hook up. I'm doing the relay so do I spice them together with the remote wire or just hook remote wire to pin 85 and not use the antenna tape it off ?? Thanks

    You need to put grounds on pin 86 and 87. You have to use the remote turn on wire on pin 85. The power antenna wire will not work because it does not see constant power, so just tape it off. Parking brake wire on pin 30 and you should be set.
