Reverse Light Wire on IS350C
I am new to all this and have decided to take on installing a Blind Spot Monitor on the 2011 IS350 Convertible but can not tap into the reverse light wire because the trunk has a double hinge and will tangle and rip out a trunk wire. So I am trying to find an internal wire and am on day three of looking. Does anyone know the best place to tap in and what colour wire that would be for the convertible? Ideas have included the ECM but even that is under the hood and quite difficult. I have tried under the door sill but a bundle of about 80 wires makes that hard and, again, I do not know the correct colour. My best bet might be the bundle running into the trunk but all the roof gears makes access very tough there too, and again, wire colour unknown. Can anyone help? I even thought I might use the stereo head as it communicates with the backup camera so must understand reverse. Again,, what wire? All frustrating as the convertible is sitting in May with the bumper off waiting for answers. We only get four months of top down weather here in Toronto. no lol.
