So the two websites dont have any info on a 09 honda fit. Can anyone help me out on this please? TIA Kahne

So this is my 1st install and I think im doing alright got everything ready to go in. I just have 2 quick ?'s. I am installing the AVIC-F90BT with a Metra wiring harness #70-1729 and also have the Metra antenna adapter #40-HD10. Ok so all 3 pieces have a blue power antenna wire. My ? is do I splice all 3 together or just the HU to wiring harness or Power Antenna to HU or Power Antenna to Wiring Harness? Also If I don't have a backup camera I don't need to hook up the revese wire correct? Thanks Kahne
