help installing new headunit with navigation
hello....
I didn't have a problem installing my eclipse AVN headunit into my last car (subaru impreza) but i'm a little hesitant with the yaris. I've looked over plenty of technical specs, bought everything I could possibly need, but I just wanted to check a few things... Is the ECU/ECM under the hood? Will I be able to get to the Vehicle Speed Sensor (I believe it's violet/white) easily without removing anything? I need to tap it for the navigation. If it is under the hood, where are the holes in the firewall for me to run the wire into the interior? I believe I have everything I need to remove the headunit. what's the best wire to tap to simulate grounding to bypass the safety feature so i can watch dvds while driving (no i really don't plan on doing this, but i don't like restrictions). I was planning on just tapping into a ground on the wiring harness itself. Lastly, I will need to run the GPS antenna to the top of the trunk. What is my best path? I'm planning on running from the headunit across to the door sill and underneath the carpet probably on the driver side. thanks for any help you can provide |

i've put it off long enough trying to get some research but haven't found much even with shop manuals and i can't say this thread has gotten many replies.
i'm going to call the parking garage today and try to park somewhere on the street (really hard to do in manhattan) while I poke around and try to install my eclipse AVN. my concerns: - popping off the center dashboard pieces so I can remove the stock radio. - finding the ecu and the vehicle speed sensor (is it under the hood?) - finding a hole in the firewall to get a wire through to the ECU. is there one on both driver and passenger sides? i already bought the wiring harness and double-DIN dash kit (to fill in the sides). hope that is all i need besides some random wiring stuff I already have. |

Check with Crutchfield, they might be able to hook you up

found this thread through the similar threads search. yay!
http://www.yarisworld.com/forums/showthread.php?t=4920 says the VSS is INSIDE the car, whew. I guess it's also at the ECU, wherever that is, but as long as it's the right wire, I can tap it from anywhere. thanks for all the help. i probably should just pay to have someone do it like most of the other navi users on here. oh well, I'll give it a shot first. |

why install the gps antenna in the trunk?? just stick that bad boy underneath the dash where it has a clear view of the sky. no need to run wires anywhere!
