Brian and Garrett also had a Tier 3-9L. When they were finished with the engine they also were challenged with a wiring harness. Wiring diagrams were the highlight of there day for many days. They worked with their classmates and the 4 of them combined their efforts for a successful adventure. Make sure you notice the IVT transmission shift lever that is being used for a throttle. Dual channel hall effect potentiometer right Garrett?
