Why not trace the wire from the reverse light itself. That's how I hook up my reverse sensor and camera.

Look up stickied DIY. It's there.

 

I found the stickied DIYlink but it was for civics. Am I missing something??

 

im interested in this mod setup too. ill just be here reading.

 

Wire Updats:

Ok, here are the locations of Certain wires needed when Installing Navigation system:
(I Found a lot of usefull info from http://www.the12volt.com/installbay/vehiclewiring/1/yeard/Toyota.html)

1st. VSS or Speed Sensor wire:

2nd. Reverse Light Wire:

 

its just easier to wire it from the reverse lights lol

you already ran the video cable from the camera to the front so just get the reverse wire to follow with it

Yes, that is what I did for the actual camera, but in order to make the head unit switch automatically to the camera, I needed a signal that told the HU that the car was in reverse. This for me, this was cleaner to run the wire over there instead of running a wire from the HU all the way back to the tail light.

 

yeah i agree but you already have a wire coming from the tail to the front. so might as well kill 2 birds with one stone and just run them both from the tail

 

Part of the reason I did it the way I did was I didn't have the reverse camera when I got the HU so at the time i didn't have any wires ran to the tail light, and I didnt know if the HU needed that reverse signal or not.

I guess I could have ran another wire with the RCA that was going to the HU... Oh well Its done with now.... and it works.

 

sorry to bring up a old thread, but i just installed a pioneer hu and i also purchased a reverse cam, turns out it was meant for the 08 corolla not 09 :facepalm: so i am ordering a new one. my question is how do you do the wiring to the hu from the tail light? or how do i wire the hu so it knows when the cars in reverse, sorry electrical just isnt my thing

 

okay. for power you would tap into the power wire of the reverse light. you'd then run the video cable up to the headunit, plugged into the appropriate port, the pioneer i had, had a specific brown port. for your head unit to sense whether the car is in reverse or not, this is where you'd tap into the reverse wire found in the fuse box, as shown in the picture above. the pioneer headunit should have a purple wire tagged as reverse, and you'd use that one. for the wires you want to tap into, use a t-tap connector, then the wire connecting to it would have a male head that inserts into the t-tap connector.

 

Instead of tapping into the reverse wire can I run a wire from the already tapped taillight to the back of the hu? Also where is the best place to run the wires ? Along the door trim or where ? Thank you

Thank you very much, exactly what I was searching for long time.
