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.
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
