I can just hook the tach input to the white wire coming from the gauge cluster correct? as that is the tach wire coming from the pcm?

 

That's how I wired my Autometer shift lite.

well ****, i got the white wire and its not working. i wiretapped the white wire using a red wire tap.....

the light does have ground and power though b/c it will let me set it up, just wont flash at the rpm level.

i set it at 2100 rpms and revved to 3500 and it didnt do anything.

 

use the white wire on the red connector comming out of the pcm

 

There is more than one white wire going to the cluster. You need the one in cavity "D5". Same wire that is in cavity "D" of C230 (and pin 13 of the pcm red connector).

 

you are a god shoebox. i didnt use that wire cause it looked more cream than white. what does the other white wire do? just curious

got it working, shoebox

 

The other one is for the skip-shift. That would be ironic for your shift light to coincide with the skip-shift light.
