Guys I put some glow shift gauges in and I have all of them woking except the tach gauge. I got it free with my order so i figured I would use it. I cant figure out which wire on the PCM it connects to? Does anyone know or have any advice on connecting it. The boost and vaccum gauges are working great but the tach is causing me some trouble.

 

this is from the autometer site. it seems to require you to buy the tach adapter for distributorless systems. not sure what would happen if you tried to connect the tach directly to that wire, or if the glow shifts even require it.... maybe not as clean a signal? idk. i have never installed a tach on a newer car before. hope this helped anyway.
