Ok finally installed the reversing
camera today, took me about 4 hours. Longest part was running the cable underneath the car and cable tying it.
First of all you need to remove the glovebox. Open the glove box and on each of the sides squeeze the glovebox inwards so the tabs on either side pop out and then the glovebox easily comes out. Now you will need to locate a grommet in the firewall in your engine bay that you will use to run the yellow plugged RCA cable through. I used the grommet near the second battery space on the left hand side of the vehicle. I shoved a screw driver through the grommet to make a hole. I then had some spare cable lying around so i shoved that through the hole. Once this is done, you can tape the yellow RCA cable to the wire and then pull the cable through to the interior. You only need around one metre of the RCA cable inside the interior. I used some automotive silicon to make sure the hole i created in the grommet was sealed nicely.
Next thing is to run the other end of the cable down the firewall and underneath the car. I ran mine along the left hand side of the vehicle with the fuel line and then along the wiring harness half way along the car. Cable tie as you go pretty often to make sure it is secure. I ran my cable above everything whenever i could to prevent sticks and what not snagging the cable. I also used black ties to make it more stealth. If you choose this same route, you will find the fuel tank gets in the way. I used some yellow tongue (im a sparky so have it lying around, if you have sparky mates good idea to borrow it off them or if you know any chippys ask them to get you some off some tongue and groove boarding) or you could use push rods or anything stiff and skinny. I poked the yellow tongue above the fuel tank and followed the length of the chassis rail until the other end popped out over the rear left wheel. Tape the RCA cable to the yellow tongue, get on the other end and pull the rest of the RCA cable through and cable tie as you go.
Now you need to remove the rear left hand light assembly. Open your tail gate and there will be two 10mm bolts in the side. Remove these and then pop the tail light out and disconnect the white plug from the bottom.
Now you need to locate the
reverse light wires. Look at the two wires going into the back of the
reverse light and note their colours. Im not sure if all hilux series are the same but my colours were as follows.
Male Plug
---------
Reverse light positive = red/blue stripe
Reverse light negative = white/black stripe
Follow these wires to the male plug side and see which pins they go into. Then look at the female plug pins and see where they correspond and you can work out which wire is for what. Easy. If you wanted to be totally sure you could use a multimeter but this is by far the easiest way to work it out.
For my car....
Female Plug
-----------
Reverse light positive = red/white stripe
Reverse light negative = white/black stripe
You now need to get the cables that came with the unit that have the red and red/black cable connected to a small black box with a skinny female plug on the other end and a yellow RCA female plug. This is the cable that connects to the
camera and turns on the
camera when
reverse is selected. Use wire connectors to splice into the
reverse light cables or use bullet connectors. Do as follows.
Connect the red
camera cable to the positive of the
reverse light. Now you can do this on the light assembly side or the car side, i did it on the car side so instructions will reflect that. So i connected the red
camera cable to the red/white stripe cable as above.
Connect the red/black stripe cable to the negative of the
reverse light. So you would connect the red/black stripe
camera cable to the white/black stripe cable.
Now somewhere along the
camera cable you need to divide the two parrellel wires and you will need to tap into the red positive cable with the thin red cable that is running along the yellow RCA cable we earlier ran underneath the car. Again use a wire connecter to crimp into the positive red wire of the
camera cable with the thin red cable on the yellow RCA cable. This provides the signal that goes back to the unit to tell it that
reverse has been selected and to turn the CAM display on the unit.
OK so now all the wiring in the rear has been done. So cable tie it neatly to where ever you can to keep it up and out of the way. Its also a good idea to wrap all your electrical connections with electrical tape for some added protection.
Now with the head unit removed, you need to run the metre of the yellow plugged RCA cable that we ran earlier into the interior up into the space where the head unit goes. You will need to plug the yellow RCA plug into the female RCA plug labelled CCD AV IN. The thin red wire that runs with this cable needs to be connected to the BROWN cable labelled CAR BACK. This is the wire that received the signal from the
reverse light telling it to switch the CAM display on.
Now you can go back to the rear of the car and plug the
camera into the wiring harness we earlier wired up and choose a location for it to go. I used blue tac to mount the
camera to work out where i wanted it to go. After playing around with it i decided best location was above number plate on the left hand side of the centre hole used to mount the tool to lower the spare wheel. You can bend the
camera mount to suit the angle you want. Also you can rotate the lens to adjust the horizontal level of the picture. Takes some fiddling around but you will get there. I then pre-drilled the holes using a drill and screwed some tec screws to permanently mount the
camera. Once screwed and mounted you can play adjust things to get the best angle of view.
You can now screw the unit back in and put all the trimming back on and reinstall the glove box. Job done and looks great! It really is quite easy just takes some time.
Once i receive my digital tv tuner i will do another write up. In regards to the GPS antenna, i just chose to let mine sit under the unit just resting there, if i open my glove box i can access the antenna easily and bring it up and out from behind the dash if i do need to get a better signal if the need ever arises but for now it works fine every time.
Good luck!
