MAKE SURE that if you do not shrink tube these connections, use a good elec tape (scotch 33+) and wrap them well. On the 7806, connect the output wire to the red (pin 24) positive camera wireĪnd finally, connect a butt connector (or solder) the white (pin 21) camera ground and run a 18ga wire to the same ground point as the 7806 center pin On the 7806, ground the center wire to a ground point in the car or the HU harness ground. On the 7806, connect the input wire (fuse holder) to the reverse wire (pin 5) - I would use a butt connector and twist the reverse and 7806 input and run into one side while the aftermarket HU runs into the other On the RCa cable, connect the sheilding wire (neg) to the brown (pin 23) wire. On the RCA cable, connect the center wire (positive) to the black (pin 22) wire. This wire also will connect to your HU to tell it that your car is in reverse (This is what switches the HU to the rear view camera when you put car in reverse) Note on the reverse wire: This is where we are going to get the power for the camera, reason being is that it turn on ONLY when the car is put into reverse and it is a 12v wire. Now, for the next steps, you can either solder or use a butt connector, up to you and how comfortable you are.Īfter you have snipped the wires off the harnesses, strip away about 1/3 inch of wire from all 5 (including reverse wire) (pat self on back) This is exactly the same conversion type used inside the Toyota factory radio. Now you have made a $2.00 voltage converter. To put this together, do the following (this requires soldering)įirst using a 6-24 machine screw (about 1/4+ in length, cut a longer one if you have to) attach the 7806 to the heat sink The 7806 is a simple transistor that will convert 12v to 6v but with a high end limit of 1.5amps, perfect for a small video camera. Now, before you go and connect anything, we need to build our voltage converter. You will also need (and most aftermarket radios with built-in Nav require this)Ĭut off the insulation to the wires to expose as much as possilbe (you will get about 4 inches) and snip off the wires as close to the harness connector as possible (without cutting other wires) Now, on the Toyota 4Runner (I will use a 2008 model for reference) locate the 26 pin harness (B for technical reference), pins 21,22,23 & 24 these two ports cost a whopping $1.23)Ģ0mm fuse holder from Radio Shack ($2.99) with 1.5amp fuse The factory camera built into the 4Runner as well as other models runs a 6 volt current, not 12 volt, so we need some items to make this work.ĭO NOT go out and spend a fortune on voltage converters it a waste and I will show you how to make one for under a buck fiftyįirst off, you need a few things to startĮxtra lengths of 18 gauge primary wire (white, black, red, etc)įrom a 7806 transistor and heatsink (part# 497-1445-5-ND & HS278-ND, I use digikey due to very cheap and good service. This came about when my Wife had it with the E7008 and wanted an upgrade to something more flexable and user friendly. I been a lurker for years and have posted a few times, but I wanted to put this up as a solution for those that are looking to put in a aftermarket system in their 4runner but want to use the factory rear view camera (You know the nice one built into the rear gate?)
