Integrate Speed Sensor and Dakota Digital VHX

[jgmccrac]

I thought l'd pass on how I managed to integrate the speed sensor from Dakota Digital's VHX with my Dominator EFI system. I used the A4 input signal wire from the 558-400 harness, and I tapped that wire into the "SPD SND" wire on the Dakota Digital Control Box. I then setup the system as per my pics below. I had to play with the pulses until I found my speedometer was accurate. I had researched this heavily on the web and found nothing, and so I'm posting here my approach for future users that may want an easy solution with Dakota Digital systems.
