Should be blue. And I believe black is the ground color. It was a while since I did mine.

And the passenger kick panel is where the reverse wire is located. I'm not sure which plug though but it is blue.

I assume you're looking for a +12 headed to the backup lamps when the car is placed in reverse? The left backup lamp is Blue/Black. The right backup lamp is Blue.

As for getting to that signal sooner, the reverse signal also finds its way to the mirror so that it drops out of dim mode at night if you put it in reverse. There should be a blue wire (pin 2 on the regular ones, pin 9 if yours has the Homelink system included) that indicates 'reverse'. That signal works its way back down to the back of the junction box under the left end of the dash, but is NO fun to access. From there, it heads back to the transaxle where the actual switch is located.

 

Thank you I will remove the passenger side kick panel tomorrow and try to find either of the blue wires.

 

If you can access the junction box, Pin 4 of I/P-B and Pin 14 of I/P-N are the wires (both blue) leading to the driver's mirror from the transaxle switch. The actual power wires from the transaxle switch rearward to the two backup lamps don't pass through the passenger compartment at all, and although they are blue and blue/black as they leave the lamps as noted above, they change color in the harness on the way to the transaxle switch, so beware if looking for another alternative.

 

finding needle in the haystack

OK so I will not find the blue wire in the kick panel of the passenger side correct?

Therefore I have to find the junction box or can I find the blue wire from within the rearview mirror or by removing door panel?

Got any pics of what the junction box looks like?

No, it's above your left foot where you'll find the junction box. It's just that it's a right pain to access to begin with unless you're a contortionist, and then you have to sort out which plug you're after with a flashlight in your teeth. Just sayin'

 

Reverse Light blue + passenger kick, red 20 pin plug, pin 2

according to a remote start forum this is the reverse light? anyone explain what 20 pin plug, pin 2 means in simple terms?

 

Dont cut the wrong wire!

Sorry for the long thread....

I think I found the junction box (molex connectors) but I am unsure which one is Pin 4 of I/P-B and Pin 14 of I/P-N. I understand what Pin means but what does "I/PB AND P/P-N" refernce. I attached a PIC of the junction box.

I see a white on, a blue one, brown one, and green one. (All have blue wires). Which Molex is I/PB and I/PN?

Just came across this article regarding locating the Blue wire. Some Hyundai vehicles DO NOT have the blue wire on the RED plug in behind the switch panel above the fuse panel BUT the 4th pin from the bottom left which has no wire in it DOES activate when reverse is selected. So all I did was strip a 3mm wire about 8mm and slide it into the plug so it contacts the terminal then connect it to your revers camera activation wire.

 

Its the blue wire on a red 20 pin plug. its pin 2.

 

Those are the connector names.

Now that you've already done the hard part, the rest should be easier.
One of the harnesses on (I think) the right side of the tan/pink connector on the top of your drawing should have 4 wires - one gray (12), one green (11), one black (13). The last should be blue (4). If you can spot that, you've found your 'reverse wire'. It gets +12 whenever you're in reverse.

 

Bob - we seem to have a disconnect. Where are you locating this red plug, and what part of the reverse power to the mirror (or whatever else) is passing through it? I get the impression you're finding 'reverse' somewhere else, which would be OK, if it were possible to find it.

 

Got it

IGNORE ALL MY OTHER POSTS REGARDING THIS MATTER I WAS ALL WRONG.

How To Tap Into Reverse Light For Backup Camera
1) Disconnect battery
2) Remove fuse panel cover
3) Remove Fog-ESC-AWD switch panel (push out from behind)
4) Remove Red Connector
5) Remove Electric tape from the Red Connector wiring
6) Tap into BLUE wire with wire tap connector
ie. Posi-Tap- No Crimp Tap
7) Done

***See PIC For Reference****

FYI: I went with a pioneer backup camera connected to a Pioneer Double Din AVH-X5600BHS
500% improvement in sound over the stock unit.

p.s. IP B means Instrument Panel Socket B Instrument Panel is located above the fuse panel.

And if there is NO blue wire on the RED plug (only cars with auto dipping mirrors seem to have it) Strip a wire about 8mm and insert it into the red plug in the left hand row 4th from the bottom That is the pin to activate the reversing sensor. and replace the plug

 

You'll find IP-N is the other socket.

Glad you spotted it. No fun to get to, to be sure. Take it you found the four wires as described earlier, with the blue one on pin 4? Tough to tell from the photos.

 

CANDERSON…THANK YOU!

Based on Anderson instructions I found a RED PLUG above the FUSE PANEL in the upper left corner of the junction box. PIN 4 is blue, when I tapped into the BLUE wire in PIN 4 i got power when the car is in reverse so the camera engages.

Apparently there also is option to tap into the reverse light behind the passenger kick panel. I DID NOT CONFIRM this option but apparently there is a red 20 pin plug and PIN2 is also for the reverse light.

Thanks again for all those that posted on this thread to help me out. Project complete!

 

If possible please provide a close up image of where you connected, I think I see in the pictures above it looks like on the red connector there is a blue wire at the bottom of the connector with a red tap that a violet wire is also attached, is that true?

 

The purple wire you see is tapped into the blue wire on the Red Connector pin 4. The purple wire goes to the receiver. The purpose of the purple wire is to activate the rear view camera when the car is in reverse. The pics I posted show you what it looked like after I finished the wiring not before.

 

Right. Saw the barrel splice, but in that confined space, the flash kinda wiped out the wire colors!

Really glad you located it and have it working now. How's your back? I used to hang around upside down under dashboards, but I'm getting to old for that stuff these days. The door sill is too hard on the back.

 

what kind of unit did you install? was it real expensive? where did you get it? what made you choose the unit you bought?

Not the easiest project to tackle but well worth it….

Pioneer/Alpine is all I install in any of my vehicles.

 

Just a quick note. My 07 Santa Fe gls does not have a blue wire in the red connector behind the ESC panel/over the fuse box on the drivers side. Nothing connected to pin 4. I have been hitting every blue wire I see under the dash and so far they are all hot, in reverse or park. I really don't want to run a reverse power from the back to the front like I had initially done my installation. I read all of your notes Santa and various other folks notes, including the passenger kick panel approach. However, I mangled up my red wire, so I ordered 50 more feet today from Amazon, hanging head in shame.

I am disabled and I cannot get on my knees or even sit on a surface without 22 inches for me to stand under it. I took out the glove compartment, and I see a huge bundle of wires from the harness, but I cannot find a junction box that was talked about.

If i purchased a thing ma jig, I don't even know the name of the part that goes into the 16 pin red socket on top of the fuse box on the drivers side. But in theory, if I could salvage a wire someplace from an auto shop trash can or something. Would it be reverse power if I inserted it into the red socket and plugged it into the receiving end?

And, why don't I have a blue wire in that socket? Seems like everyone agreed my model year more or less would have one in pin hole 4. I found the numbers 1 to 8 and 9 to 16 on the beige receiver side of the socket and tried testing it with a probe, with no luck, but its a kinda odd path it gives wires in there so I am not sure the probe made it in. I tried the blue wires I could see on the other two sockets to the right of the red socket, with no luck either.

 

on the driver side kick panel I found mine its a brown wire in the main Harness hope this works for you

 

Camera cuts out when braking

I installed an aftermarket Android unit and everything works fine - except the backup camera. I took the 12v power for the camera from the backup light at the bulb and I took the 12v reverse signal from the red connector (pin 2) located underneath the passenger side kick panel.

PROBLEM: the camera works great when I put the car in reverse, but the instant I hit the brakes, the picture cuts out. It comes right back when I let up off the brakes. Perhaps I connected to the wrong blue wire? I guess I'll have to fish it back over to the other side and try to pull the 12v reverse signal from underneath the fuse panel.

Would it work the same if I just tapped into the 12v power right at the point where I'm drawing the camera's power? It seems easier to run the 12v reverse signal wire to the back than contorting myself under the dash.

Any input or suggestions would be appreciated.

Thanks

 

Where are you physically locating your camera display? Your Limited has a reverse signal (and 12V and ground) up in the rear view mirror wiring. Reverse signal is +12V.

 

The display is an in-dash unit (Ouku or something...Chinese of course) and the camera is located just above the license plate.

Just as an experiment, I ran the reverse signal wire to the back and tapped into the blue wire for the reverse light and got the same result - when I stepped on the brake, the picture cut out.

I haven't tried tapping into the connectors behind the fuse panel on the driver's side yet. Are the wires for the rear view mirror located there?

 

Mirror "reverse" is under dash at I/P junction box (blue wire) as others have described. PIA to access for the most part unless you're a contortionist. If you've hit the right wire, there is NO reason that applying brakes should be shutting down the signal. For an automatic, the signal comes right off the transaxle range switch on top of the tranny .. nothing to do with brake circuit.
