I want to install a back up camera on a 2013 altima and need to now what wire is the reverse light wire

Connect rear camera power lead "Red +12VDC" to back-up lamp circuit in trunk. Splice into back-up lamp wire near bulb. https://www.6ya.com/callphilipforhelp

These are on pins 5 and 6 of either tail light assembly. You can splice the backup wire to the wire on pin 5. For the ground, trace the wire from pin 6 to where it connects to the frame. Attach the camera ground to the frame there.

Take out the rear tail light and see which wire feeds the back up light. That is the feed wire. The system grounds to the body.

There may not be a wire in the dash, the connection depends on the shift lever's possition and usually a switch near the shift lever that turns the reverse lights on. If there is actually a reverse light on the dash, look for the wires to and from that light.

one wire on solinoid should light up test light when switch is pressed witch then should power control mod and then shifter motor when switch is reversed it should send power to control mod and shift out of rev i dont have schematic in front of me but should work in same sort of manner try google search 2013 harley trike reverse schematic there is a reset video on you tube as well as a hdforum blog on the reserse system good luck this is vid link http://www.google.ca/url?sa=t&rct=j&q=&esrc=s&source=web&cd=6&cad=rja&uact=8&ved=0CDAQtwIwBQ&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3D8LAzdoMe96I&ei=wcUkVNysO4mPyAStzYHIBg&usg=AFQjCNHvOFAidKwM-dPI1ObfCc1yh0m3iw&bvm=bv.76247554,d.b2U

It's so simple. According to international colour code the +ve wire should be either red or yellow and the negative wire should be black or blue. you need to secure the camera power wires to the right wires of the rear lights and it's done. the image signal cable wires should then be connected to the LCD screen on your dashboard or a detachable one.

ASE Mechanic:
with out any schematics you can trace these wires down by finding the reverse lights, and disconnecting the bulb and installing a test light, and with a buddy put in reverse while you check to see which wire gets hot!!!!!!!!!!!!!!!!!
