Did you still need help on this?
What is the Brand & Model Number of the Wiring Adapter?
Did the Factory Radio or the Radio prior to this install work?

Yes I still need help. The radio before this install worked fine just the display went out. I don't know what brand the wire harness is
Expert:  Don 'Mo Lurch' replied 2 years ago.
Problem with not knowing the Wiring Adapter is your 2008 operates from DATA by the vehicle BCM (body control module)to turn it on.
The "correct" Wiring Adapter is a must of the Unit will not work & can cause damage to the BCM, if it is the wrong Wiring Adapter.
Please Test the YELLOW & RED wire of the Pioneer for Voltage + with Key ON.
Be sure the BLUE or BLUE / WHITE wire of the Pioneer & the Wiring Adapter is connected & there is Voltage + on that wire with Key & Pioneer ON
let me know what you find
