HowTo: rear backup camera mod

JA, Wired the switch today following your instructions. Same thing, the rear camera is on when the switch is off and in reverse. When I shift into drive and turn on the switch nothing happens. I believe I may have a bad relay and it is not making the camera come on when in drive. I wired as you said and double checked the connections. I am using a 5 pin 12 volt relay the reverse side of the relay works but not the drive side. The switch is a 3 pin rocker switch with a light ( one negative pin, one power pin and one acc. or camera pin.


Thanks for your help with this, I will keep trying, Im sure your instructions are right I am just having some issues with the project.

Being in drive has nothing to do with it. It would work while in park as well, if wired correctly.

While in park with key in ignition and vehicle on (but no need to be running)...turn the mod switch on, do you hear the relay click you should. If not the coil (85, 86)of the relay is not wired correctly. 86 needs a full time solid ground. 85 should be wired to the ACC pin on the switch.

Where are you getting power from for the switch. Does the led on the switch work?
 
JA assisted me with my set-up...i will post pics/tips tonight.

Ah yes, I do recall that now. About a year ago i believe or a little less. I knew we should have done all that work on the forums and not PM as this seems to be a tricky mod indeed. Maybe you can help, how has the mod been going all this time?
 
Success!

OK here we go. Very special thanks to JA for assisting me (via PM) with this.

For this mod I went with a factory parking sensor switch from the FJ or any Toyota that uses it. Think it was like 70 bucks or so. I like the stock look.



I never took pics for a write-up but this mod is super simple and I will just list exactly what I did per JA's instructions.

1) Cut the red/yellow navigation wire located here.

2) Buy switch, extra wire, taps etc... I bought Posi-locks and Posi-taps. Very clean and easy to use.




3) Lengthen and attach both ends of the red/yellow navigation wire you just cut to your switch you bought. Attach the cut end of the nav wire that is closest to the navigation unit side into pin #30 of your switch. Attach the cut end of the nav wire that is closest to vehicle side into pin #87a.

Next, from you switch you bought, run wires from pin #87 and pin #85 to a 12V+ source. I used that accessory harness that is unused floating around in the console near the shifter. Think its for the cigarette lighter accessory package. Nevertheless, tap into an ignition/accessory source (rather than constant) so it will power up when the vehicle is on/accessory mode.

Next, from your switch, run a wire from pin #86 to your ground connection on your activation switch/button. Pin 3 on my toyota switch is ground.



Those 2 red wires you see are from pin #87 and #85 from the switch. They tap into the pink/blue stripe wire from that accessory harness which is 12V+.

The black wire you see is from pin #86 and runs to the 3rd pin of my button/switch ground.



Next, on my button/switch, the first 2 pins 1 and 2 are only for the illumination circuit which allows for the light bulb to be activated when pressed. JA gave me the brilliant idea of just tapping into the same pin wires from an adjacent switch (hill decent control button).

Lastly, pin 6 on my button/switch I tapped into that cigarette accessory harness I was referring to earlier. I tapped a white with black stripe wire which I believe is a 12V+ source.




Thats it! Simple as that. This is not a formal write-up just a simple "let me show you what i did" kind of thing. Let me know if you have any question about what I did. I have a medical background so don't expect me to answer any complex electrical questions.

I use this mod mainly for switching lanes and eliminating blind spots. It is pretty incredible in traffic. Its also good for staring at people behind your Runner.

Special thanks to JA for holding my hand!

I've got to do this mod sometime this fall. Use of the camera at anytime would be very helpful. Thanks for the easy write up and pictures!
 
I should be doing mine next week, looking forward to doing it and thanks to everyone who has clarified it for those of us that aren't very knowledgeable in this stuff.
 
Finally The full time camera mod is done.....working and is now another project completed. For all that want to do this, it is not as difficult as I made it to be. With the help and write ups by J.A. it all made sense. His first write up was too techinical for me, but when he made it clear with using a simple 12 volt relay it became easier to understand. I follwowed his instructions...this is important because he is right on with this! I made the mistake of placing the RED=Yellow wires backward on the relay pins 87a and 30, as soon as I reversed these wires the mod was successfull. It does everything you will want, no more engine check ligkts, no more backup lights on in drive...it works like magic.
A special thanks to J.A. for his work and for sharing this with amatuer electricians. Thanks to all others that followed this post and to the T4R.ORG forums, I have been trying this mod for a long time.

Glad to see you got it working! what switch did you use? Any pics of its installation/location?
 
I used a Carling SPST lighted rocked switch. Mounted on the center console next to the down hill assist switch. The camera is an Eclipse BEC 106 I'll try to send some photos in the next few days I can't believe it is in the 4 runner and working great. I would never had figured it out without your help.

J A, A few photos of the switch location, one photo of camera on when in reverse and one of camera on when in drive. Of course I think that Snesley's switch look more factory like and I may got to that later, thanks all that heped with this.

Very nice, I hope to get to this next week myself. I have a couple stock switches that I'd like to use in addition. Good job dwinev!

Yes this is the relay you need, you only need one relay and a switch, then follow JA's instructions and you will be done with this mod.

Looks like the exact same relay I used. I tapped into 12 volt power from a fused power supply from the accessory line so I did'nt need the fuses that you have. If you are wireing direct to 12 volt power than you should use the fuses. Good luck This is a good project.

I'm not using them, they just came with the pack. It was cheaper to buy what I have then just 2 relays
