PIE Adapter Wiring

[Aretoo]

Hey I have had a PIE adapter installed now for about 5 months. When I wired it in I used a power supply that was ignition controlled. It has now driven me officially nuts having to switch to my AUX input every time I start my truck.

I was wondering how you guys wired your in? Did you wire it in to a ignition controlled power source or a always on power source. If you wired it to always be on do you have issues with it draining your battery? Thanks for the help.

I had mine wired the same way, and I agree that it was annoying to have to put it in aux every time. I never did anything about it though. I think it's more of am issue with the truck stereo and not the PIE adapter, seeing as how it was originally intended to be a rear DVD player and you wouldn't want it coming on every time. I don't see why the PIE not having power until the stereo would affect the stereo not switching to aux, especially when it had a dedicated plug.

It is due to the fact that when the radio starts backup it does not see a source coming from the PIE input so it switches do the default FM radio. If the PIE was wired in hot all the time when the radio came on it would see a source there and not switch to FM. I had a similar setup on our Ford Escape (almost same radio) and wired that one hot all the time and it would not switch. I was not sure if it would drain the batteries too much leaving it hot all the time since these trucks are harder on batteries than an Escape.

Anyone else for how they wired their PIE adaptor?
