I am installing a NAV head Unit in a 99 SC400 with Nak System" Sony XNV-770BT ", and I need help finding the Reverse cable up under the dash...color and location is good "I am doing a Camera with the install, hence the need for the reverse wire"

Hell, I hope I dont become the victim of radio theft again, though I have a remedy waiting for them this time round.

Tell me your thoughts on the HU also

I had this posted in the electronics section, but was not receiving any input, so I am posting here....in an effort to get a faster response.

 

I think audio section would help, pm Raine he know his stuff

 

directechs doesnt show the wire color...easiest way would be pull a reverse light and test to see which color wire shows 12v+ in reverse.. then look in drivers kick harness to rear and see if u can find the same wire...worst possible case is run a wire from the the rear light up to the radio
