Does anyone know where on the Challenger you can get a tachometer signal?
Can't seem to find any info on this.
Need to find out what wire to use.
2010, 5.7, auto, if it makes any difference.

Thanks, Brad

It looks like there a place on the PCM it can be done but some places say you need an adapter to do it and I never have tried it so that's why I didn't chime in. No info if better than wrong info. Wish I could help
