I removed my Autometer shiftlite from my 95 Z and I want to install it in my 99 SS. Anybody have wiring diagrahm or know where I can find 1 to hook this thing up?

 

The tach signal is the #10 pin on the front(closest to the nose)pcm plug. It's a white wire. You can get a 12v switched power source from the pink wire on the asr if you have it. Otherwise, any pink wire is suppose to be a switched 12v source. A ground is easy enough to locate.

 

wire it through that grommet in the firewall right under the pcm...punch a hole vs cutting a slit...i've seen a few guys cut a slit and over time it wairs down the shielding of the wire...

I have posted and looked for this info for a while now, thanks!! I just left it alone until I could find it. It looks good when you get that initial flash when you turn the key over anyways!
