I ran the red to an ignition hot terminal on a Painless Wiring fuseblock, black to ground, white to MSD tach output, violet to a terminal strip so I could hook everything needing an RPM signal to that. 2001 Dodge Dakota 408 All Motor 11.27 @ 117.83 mph 2017 NM Mopar Challenge Series Champion.

I would think both are off... those chips arent all that accurate ... dont know why it isnt seeing idle RPM... do you have the booster on it (I think thats what they use to use with the Sun tach and MSD..... I want to find a 3" to 3.5" tach for my Rampage... I've got the 5" tach but thats too big
