Has anyone tried to tap it off of the back of the gauge cluster? When I installed my Eclipse AVN 5510 in my old car I just tapped it off of a signal wire on the back of the gauge cluster and it worked perfectly. I was reading in the sticky above about tapping it off at a few different connectors but it seems like there are a few different answers and no definite yet.

 

depening on the yr of ur car i would just buy the module harness and be done with it

 

I have an 06

 

ya nothing for us guys there... unfortunately i have no idea man but if you figure it out let me know. ill probably install navi in my car sometime later on in life

 

Yea I'm gonna ask my buddy tonight. He's been doing audio installs at Best Buy for the last 4 years through college. I'll have him check his install instructions to see where they suggest to tap it from.

 

I pulled VSS off the module in the engine bay, works excelent. I searched for a couple days on the Net and couldn't find another location to pull from. Have 06 SS/SC and installed a Pioneer Avic F900BT.

 

which one? post it up

 

will get pictures in the next day, it was the BCM I believe, the Silver thing laying on it's side infront of the "Jump point and Fuse Box" in the engine bay. Yellow line in the 3rd plug.

Pics to come.

 

yup thats the PCM

 

here is what I got real quick, can't take the intake off before work, But it's the PCM and it's the bottom connector in the PCM, The Yellow wire in the bundle is the VSS. I soldered the pink wire you see onto it and ran it into the cabin through a gromet already there.
Hope that helps. If you need more info, I can find the posts/info I used to do it for you.

I pulled the intake and some vacumme lines in order to pull the PCM out of the holder, then just unplugged the plugs of wires from it and found my wire and then put it all back together, maybe 10 min total. (took me longer to run the wire thought the firewall)

 

That's the wire my buddy told me to tap too. I looked up the wiring diagram for the gauge cluster and the signal for the speedo goes from the trans into the ECM, which in the diagram is called the GMLAN. The GMLAN then converts the signal and sends it to the gauge.

 

lol funny thing is running a wire thru from the engine bay would be easier for me

 

V8Huntr which wire was it that u tapped into behind the gauge cluster?
