Hey guys, I have searched and searched and can't find the answers to my questions. I'm wondering where I tap into the power installing these items, some requre "key on power", some requre "ACC" power, the bluetooth requrires "always on power".

Items:

Pioneer avh p4100dvd
swi-ps
bypass chip
Pioneer blue tooth module

I also have a bypass module (didn't want to mess with a toggle switch)and it says use "accessory power". Can I tap into the lighter for this? The two power connections for the radio I know are taken care of in the harness adapter, which brings me to my next question, on the pioneer side of the harness it has a ground wire, but there is a ground wire on the scion plug that the adapter plugs into. Do I need to chassis ground the wire coming from the pioneer plug in, or does the ground in the harness handle it so I don't need to find a chassis ground.

Thanks in advance.

 

Of all the people looking at my question, nobody can answer? I have searched this site up and down, and I can't find a thing that answers my question.

 

Were you ever able to complete your install, because I'm having a similar issue. I wanted to know where does the white wire connect to.

 

anyone doing installs like this needs to go pick up an auto-ranging multimeter.. learn how to use it and you'll love it.. your ACC/on with key power will be behind the radio, so will a constant.. it's just easy to tap it there since you are adding radio accessories anyway you can have all the wires going to the same place, zip tied/taped together to be neat and tidy..

Constant = Blue w/ Yellow Stripe
Accessory = Gray
Ground = Brown *or any bare metal behind dash*

Use a meter to doublecheck any wires
