Ok my question is I am getting a In dash pioneer 7 inch screen with cd built in, I already have the brain avm-p7000 for it, now my question is do i hook up the wire harness for my speakers and all to the head unit and then just cinnect the brain to the unit, or do the speakers wire into the brain, i haven't seen the head unit yet i get it 2 days. and I am looking at the brain and i don't see were all the speakers would hook up to there are only hook ups for 2 speakers not all for so i am kinda confused so anyone that has this set up or a similiar one that needed a brain unit, please helpme out thanks

 

The Pioneer wiring harness that would normally be at the back of the radio is on the "brain" unit. Actually if you do not have the harness you will need to get one because it plugs into the brain (the same way the harness would plug into the back of any other radio). It is a pain depending on where you mount the brain because from there you need to run the speaker/power/ground wires back to the area of the head unit and wire them into the corresponding wires coming from the vehicle.

Note: This is from my experience with the AVMP8000R, I cannot guarentee that the AVMP7000 work in the same manner although I would suspect it does.
