I'm trying to install a Dakota Digital Box. I have all the wires needed except the tach wire from the stock tach. Where is the best place to tap the stock tach wire from? What color is this wire? Does anyone have a wiring diagram for the cluster? thanks

 

Locate the 2B wire and use that.

 

Thanks for the info... I have found out my tach is bad. I did a ohm check of the wire from the ECU plug (2B) to the cluster plug and the wire is good. Should i do the repair on my tach or just buy a used one?

 

Installed a tach i got from a local guy and still no rpm on tach. I'm gong to do the Tach fix on one of them to be sure both are not bad....

 

I installed a different tach and the same thing.. No rpm.. While the car is running should the red light be blinking on the unit? On mine the green power light is on and that's it.. Also how can i make sure the coil signal i am using is corect?

I think I'm going to run a new wire from the trailing coil for a input for the Dakota Digital box. I'm using 6ea bosch coils.. Which trailing coil do i use for the signal wire? T1, T2 or T3? thanks
