Erm, not quite lol. When we got the car a couple of years ago it had an aftermarket head unit in, an old Xtrons unit (all works fine, sat nav etc) although the camera has never worked. At the loom in the dash theres the usual wiring adapter, also the aerial, ipod connector, GPS antenna connector and a yellow camera plug marked up camera which plugs into the head unit. The camera at the back is the original item with original wiring but the head unit end seems to of been rewired. I think I'll have to go back to square one with it. I had a look at it the radio wiring today but need to look at the loom in the boot to see if theres any different wiring been done. Worst case scenario im just going to have to wire in the new camera with new wiring to the head unit. The camera is kaput so I get the impression that it did work as otherwise why would they do the wiring at the head unit end. More investigation is needed!

Quick question, on the power wire of the camera theres the red and black, red is the power obviously, where do I put the black wire? Also with the yellow plugged cable, do I slice the end of the plug off and wire that to the black on the car or would you just run the new cable down to the back of the head unit? Worth noting that theres one of these yellow plugged cables plugged into the back of the head unit (aftermarket head unit came with the car) which is marked up 'camera'. Im confused lol. I know the red wire on the yellow plugged cable is to trigger the cam input on some head units.

Cool thanks for that. Camera should be here Saturday so will try it when I get round to it next week.

So you tapped into the reverse wire for power, then connected the black to the black on the original wire, and the yellow to the yellow on the original wire? And the white you left alone? I think the PCB in my old camera is way past it anyway, seems to have completely corroded (unit was full of white dust).

Hi, just stumbled upon this thread trying to figure out my camera woes. I have a 2001 estima which uses the same camera as the earlier rx300. I'm hoping I can reference this and fix the old one in the same way as its basically the same wires etc but you have a slightly different camera housing (dont know what Lexus you have). Been quoted silly figures for even a second hand unit and was going to try a cheap Chinese camera but modify it to fit. The bit I was stuck on was the wiring as I believe they use either 12v or 6v, or both and I was a little confused. For a tenner I'm going to try this. Thanks for doing the write up it all seems to make sense! Lol
