thanks in advance

no one knows anything????

Why would you want the brake light wire, wouldn't you want the reverse light wire?

Did you even search the forums before tossing these questions up and getting your panties in a bunch when noone answered any of your questions within 14 hours of you asking the question?


for your reverse light tap into it at the rear of the vehicle

 

[undercover_skank]

i meant reverse wire. i searched and didnt come up with anything. and i didnt get my "panties all up in a bunch" i was simply bumping up the thread. thanks for your input. and youre in olney? im not too far from you. im in vincennes

 

[ecordell]

Yea, I'm in Olney, your location says LongBeach lol, you in college over there or what?

 

[undercover_skank]

im from long beach but i moved out here planing on going to college but ended up not going. i have family out here also so i just stayed for a while.

 

[ecordell]

I gotcha, well welcome.....

thanks!

i also need to know where the speed sensor wire is located. im installing a pioneer d3. searched and didnt find anything

 

[ecordell]

Your speedometer sensor wire? I think the sensor is on the transmission, but where it goes from there I honestly have no idea......

 

[undercover_skank]

yeah i knew that. do i evan have to hook it up to the radio? why does it need the speed sensor hooked up for?

 

[ecordell]

I wouldn't think it would, but I honestly have no idea.

 

[undercover_skank]

yeah...well see whenever i get around to doing all this. just been too cold out lately and i get off work late

because GPS is inaccurate, and drops out. the speed sense wire keeps the nav system chugging along, and gets you those last 10-20 feet of accuracy. it also makes all the funky guage features work.

When I did my headrests I ran the wires under the seat frames where the recess is right about where the ear shaped bracket comes off toward the console.
That let me leave enough slack to avoid pinching them at full front or full rear or with the head rest up (yes you need slack for that)... you better get someone to move the seat while you watch the cables the first time you put them in... \\
and No, I don't want to talk about it.

 

[undercover_skank]

sounds like you learned the hard way. yeah i figured the headrest stuff out already. just the speed sensor wire and the reverse light wire i heard is in the a pillar. anyone else knows where exactly the speed sensor wire is and what color? thanks!

 

[Eagle]

i can tell you one place you can find it...
the cluster has to have a speedo wire

That would also be known as the VSS wire, and I be the instructions on installing a factory nav (avalanche forums) would include it, might even have a picture

Also the avic forums had it listed as a4 behind the cluster, according to 12volt.com it is correct.

also on avic and 12volt I learned that the back up wire is lite green at the BCM... just have to find out where hte body control module is, and look for the lt green wire.

 

[undercover_skank]

alright. thanks. ill have to search for them under there

 

[undercover_skank]

just finished and i now have engine noise! wtf! same amps and everything. before the engine noise would come and go. but its been a long while since ive heard it. and now its back. i guess ill check the grounds tomorrow

 

[undercover_skank]

[SoulRaven]
