Question AVIC Z2 w/OEM cam from JBL truck

[Someguy123]

ok so i am replacing my JBL NAV headunit in my 07 Tundra. with a pioneer AVIC-Z2. i want to use my OEM back up camera. all the write ups i have seen only cover the NON JBL system.

from what i have read. it seems that i should be able to splice the video feed positive and negative wires to a coax. but since the ground and power already plug into the head unit. i shouldnt need to run wires for that. (just for clarification, i am using the schoche harness) the K9 connector plugs into the schoche harness. which should supply power and ground just like the truck normally would.

is there anybody who can confirm this?? is there something i missed??

thanks in advance for any info.
