Send me to dat person who knows how to wire up an Autometer tach to a VG30e ECU. I need to see my revs!!

 

I have a factory white needle tach that is not hooked up to anything. Is there a way to make it work with a VG30e?

Can't you wire it to the coil like most other applications for many years?

You can't hang if your nuts haven't dropped...it's physics

If there is an ignition coil, that's where it gets wired.

Follow instructuons that came with tach.

Follow instructuons that came with tach.

...and sometimes it gets wired through the ECU...its less tedious to ask questions first.

So I hooked up the Autometer tach to the ECU signal wire (blue/orange) and the tach is working, kinda. Inside the tach behind the light, there is a square box with two switches. I adjusted them appropriately for the 6 cylinder engine, 1= up, 2= down arrangement. I do have a moving needle but it is not accurate. It stays low and jumps a bit.

 

Here is the question: With the needle jumping and low position, is it likely a tach adapter is needed?
