How easy is it to install an Autometer tach using an MSD 6AL box. On the box, it has a "tach output" port. Can I just run the tach right to the MSD box and get the signal from there? Or do I have to tap into my factory wiring? I already did a search, BTW.

 

Yeah you can just run the tach wire to the tach output on the 6al. I ran mine to the tach wire on the coil because I dont have the 6al yet.

 

Cool, thanks.
