3rd gen swap radio question?

Im running the entire 4th gen wiring harness(body/engine). Its from an 00' LS1 T56. I have the dash in also, my question is i cant get my radio to turn on(aftermarket pioneer). It seems to me that the IGN wire isnt getting power when the car is turned to 'on'. Does the IGN wire goto the BCM first? and does the door harness need to be plugged in to the BCM to get the radio to work?

Thanks,
Brandon

I am not sure about your specific application but I do know that in most GM vehicles the RAP (retained accessory power) (I think that is what it stands for) is controlled by the BCM. It keeps the accessory power on to the radio until the door is opened. So I would imagine that the BCM gets the accessory voltage when the car is on and then turns the power on to the radio. If you hook it up this way then you will need to connect the door pins so that it will turn it off when you open the door. Otherwise you will have to wait for the timer to kill the power.

yup, like the guy above me just said..
because it keeps the radio on until you open the door (or times out) it goes thru the BCM.
