After looking at several post on here. I am very confused on which two colored wires I need to tap into on a 07 Tc for the speed sensor and the reverse/backup sensor. I'm about done installing my Clarion Nav and those are the last two wires I need for it to work.

PLEASE HELP!!!! Thanks.

 

I taped into what I thought was the speed and reverse wire, but I was not right. My car doesn't move on the map. So this tells me I did not tap the correct speed wire.

I'm still needed some help.

 

search the forum for that wire....
if your car doesnt move on the map check your gps wire. The speed sensor wire is suppose to wired up and its a just in case thing for the navi when you dont have a gps signal and it tries to keep the map accurate

 

ORANGE wire on the ac cluster wires is speed.

I bleive purple behind the glove box is back up. look at the topic "D3 installed" that helped me out alot

 

Here's my update. My HVAC plug does not look like the one in the D3 install thread. So I took the orange wire that was suggested in the thread. I have two orange wires on my 07 tc. So I tapped into the orange wire on the top row on the far right side of the plug.

Guess what, that one was the correct one. Now my nav is fully functional. Now I have to mount the gps antenna and I'm done.
