Throttle controller arrived for the ISL. This is a cool piece. Made for marine powerplant updates to retain mechanical throttle cable, yet transforms it to accel position sensor and idle validation switch. Has a nice linear feeling return spring on it, comes with 108 cable end fittings, and can be converted to work with push or pull. Larger than it really needs to be, I may cut it down to 1/2 or 1/3 it's size, depending on mounting location. Will be somewhere in line with where existing throttle linkage is now, retains stock pedal and pull-turn cable throttle control. Yummy. I originally ordered this to retain and control my auto trans modulator cable, as it would still need throttle positioning reference to work properly. Then once I saw nothing is holding the Allison in the truck with the engine gone, I decided this is the time to try squeezing the 13sp in. I will still need this controller to run the engine, or could have bought a modern pedal with sensor from an over-the-road truck. No preference on my behalf, from the cab perspective, it will still look like the mechanical engine is under the hood.

Besides battery power, ground, and ignition switched power (which our engines get all already), this self-contained throttle controller is the only external wiring necessary to control the engine. Don't be scared to update to a modern electronic motor if you find one on the side of the road, they run mostly self contained. There are ECM pins for additional features, such as cruise control, dash "Wait to Start" and "Water in Fuel" lights, cruise control, etc... but they are accessories, and not required to properly start and run the engine.
