Several ways to go..
I built mine with the VANs optional kit. It uses a different weldment, or modifies the one that's set up for manual. Others have mounted the actuator in the passenger sidewall instead of the tunnel below the front seat and modified the existing weldment . Keep searching these forums and you will find pictures of various set-ups. Although manual is "simpler", the electric set-up eliminates the passenger foot interference, and I have mine set up to buttons on the stick, so I have no need to take hands off throttle or stick.
